Back before refrigeration, humanity turned to fermentation for much of our food preservation. With the help of some friendly bacteria and/or yeasts, home cooks can transmute tea into kombucha, and milk into yogurt, creme fraiche and buttermilk.

If you like to make bread, sourdough starters are an excellent alternative to comercial yeast. Catch some wild yeasts from your area/flour, or get some from a friend, order some, or ask Carl's Friends for a free piece of theirs. While starter maintenance may sound daunting, they are surprisingly robust.

Fermentation is also a great way to pickle things. Make deli-style dill pickles and sauerkraut. And then can it!

There's always homebrew, as well.

Thanks, I'm a big kombucha fan and have been thinking about making my own.

Creme fraiche doesn't require the warming, Just add buttermilk to heavy cream and wait. And yes it's crazy good, perhaps better than anything that easy/cheap should be. Screw you gum thickened commercial sour cream, I'm with creme fraiche now.

Sauerkraut is also a huge payoff for very little effort. Unless you are the only one in the house that likes it, then you are going to be eating alot of cabbage over a couple week period. One can only eat so many ruebens.

One thing I've wondered about kombucha since I first heard of it, is whether obtaining the starter culture from someone is really necessary. All of the descriptions I have read make no mention of making your own. Is it like sourdough, where you can just leave the basic ingredients out uncovered and end up with your own starter? I don't see why it wouldn't be.

also, they didn't forget to include kimchi. It's just sauerkraut with a different name (and spices), after all.

We make yogurt starting with powdered milk. Works the same, costs a whole hell of a lot less. My kids eat a lot of yogurt. I mean... a LOT of yogurt. Like on the order of four or five quarts a week.

Also, if you take fresh yogurt and hang it up in a cheesecloth for a few hours to drip the whey out, it thickens to a Greek yogurt / sour cream consistency, and can be used in the place of sour cream.

Easy. Organic unwaxed lemons. Wash. Slice. Only tricky bit and it's not that hard. Through the pole but not all the way through. Then rotate 90 deg and go through the opposite pole. Again not all the way so that you've got a whole lemon with two slices through opposite ends.

Kosher salt packed into the slices. Then into a far with a lid. Another handful or two salt on top. On the counter turning the jar every day. Give it a shake. After a week the jar will be half full of liquid, top with cooled boiled water if you like and refrigerate. Ready to eat after a couple days in the fridge. Quarter then lemons through the equator. Scrape the flesh off the peels (it comes away easily after curing) rinse the peels and chop as desired. Excellent in a greek salad.

I've been brewing my own Kombucha for a while now. It's extremely easy - and if you know what you're doing you can make it pretty delicious (i.e. not just 'original' flavored).

While there is not science to back up the claims of its health benefits, there also hasn't been a lot of research done on the subject. Perhaps its *mere* placebo, but I feel great when I drink it.

I also love the romantic idea of it. It's an ancient concoction, and one that, traditionally, no one was supposed to pay for. You make a batch, which produces a second mother, and you pass it along, giving your friends a magical elixir.

Not only does home fermentation of foods actually increases the nutritional value of many things. In Asia and in Europe, fermented cabbage is a staple. Just about any leafy or woody vegetable can be peeled, shredded, canned, fermented and enjoyed.

One thing I've wondered about kombucha since I first heard of it, is whether obtaining the starter culture from someone is really necessary.

Seems like you can grow a kombucha scoby just by combining sweet tea with some (living) kombucha, and leaving it in a warm place. But I wouldn't advise starting completely from scratch, as I believe the process entails letting a layer of stuff (including mold) grow on top of sweet tea, then turning it over and letting more stuff grow, etc. This is likely to end in failure.

Yogurt is so easy: scald milk, let it cool to 110°F / 43°C, add in a few tablespoons of plain yogurt (look for the yogurt that itself used only milk and culture), and incubate it at about that temperature for 6-10 hours. (This is where "yogurt makers" come in handy.)

Kefir is even easier: get some kefir grains, put them in a cup of milk, and leave at room temperature for a day. As the grains grow, periodically remove grains and give away or throw away. (See Dom's kefir-cube site for more about kefir than you ever wanted to know, including kefir cheeses and something called water kefir.)

Sourdough can also be easy. Start with some starter, add equal parts water and flour (rye, wheat, spelt, whatever), keep in a lightly covered jar/crock at room temperature for a day or so until bubbles form on top. Either use some and repeat, or close and put in the fridge for up to a few weeks - just stir the hooch back in to use. Freeze a backup in an ice cube tray in case the starter goes bad (as distinct from sour). Using a sourdough starter is nothing more than adding some to your dough or batter instead of yeast. Don't worry much about the source of the starter, as your local yeasts will quickly take over.

Icelanders discovered centuries ago that you can preserve food without refrigeration a number of ways. In order of edibility, they are: dry it, soak it in whey, or putrify it.

Drying fillets of cod, haddock, ocean catfish and other species makes harðfiskur, which I highly recommend as a camping/hitch-hiking food. It keeps pretty much forever, as chock full of protein, and keeps you going. Try it with butter smeared on it, it's really good.

Soaking things in whey brings us to surmatur, or "sour food". Here we're in a culinary grey area. The pungent taste of whey isn't for everyone, but it can alright if it's not too too strong (if the whey was mixed with water). No, what turns most people off from surmatur is what Icelanders have traditionally chosen to soak in whey; namely, ram's testicles, fatty meat wrapped tightly in a net, a sort of Jell-O thing made of meat from the face of a sheep (including the eyeballs) and so on.

This brings us to putrification, used in the "curing" of shark and skate. I can attest that these are probably the second most disgusting things* I have ever tasted. Reports on the exact process of making putrified shark vary - some say you bury it a meter down in gravel by the shore, others say it's enough to seal it in a plastic cask - but the result is the same: soft, gelatinous, room temperature meat that packs an ammonia punch so strong you'll see stars.

Despite the advent of refrigerators, many Icelanders still enjoy food soaked in whey and putrified food as well. In fairness, though, the sour food is mostly during the Festival of Þórri (from late January to late February), putrified skate is usually eaten one day of the year - December 23rd - and shark is just something we give tourists for a laugh.

*The most disgusting thing being a type of leg of lamb from the Faeroe Islands which is hung from a barn rafter until cured by the sea wind. The taste is, to my imagination, probably what excrement tastes like. It's phenomenally bad.

I accidentally drank kombucha while hanging out with some dirt-worshiping friends last summer. At first it was gross. Then it grew on me - kind of reminded me of pulque in a way and that instantly caused me to like it. People say it "just makes me feel good" and to this I respond, "It has booze in it." Admittedly, not much, but even the tiniest bit of alcohol - to someone who is accustomed to imbibing it on occasion - triggers the body's "I'm a happy booze-belly" response. Kombucha, that fermented lemonade you get at the hippy-store, pulque, all these things have low alcohol content but it's sufficient to get a response out of the body.
Same goes for "I dunno, I just like smoking a hookah pipe for some reason." and the always classic "I just like the smell of pot."

I don't mind kombucha (mostly the flavored kinds), but the worst thing is getting a super-excited bottle which sprays sticky vinegary liquid all over when opened. That smell is AWFUL and seems to linger forever.

I love kimchee though. And certain spontaneously fermented beverages. Let one of these age a few years and it tastes like vineger, orange soda and horse manure. Delicious.

Great post! I can't recommend enough that anyone and everyone here try making their own sourdough starter. It can be a pain to maintain, but it really is so rewarding.

Pickling is one of my favorite things to do. At the last izakaya I worked at, we used to make two five gallon buckets of kimchee, twice a week in addition to all of our other pickles. Nothing quite like the flavor of your own kimchee!

I wouldn't advise trying to make your own miso unless you have a great deal of space and time to utilize.

Pretty much every western kitchen I've worked in, we made our own pickles, kraut, preserved lemons, cured meats etc. Curing your own meats is SO MUCH fun, I urge everyone to look into it if you're into salty, meaty goodness.

Also, consider the fact that North African style preserving doesn't have to be confined to lemons. Tangerines, meyer lemons, kumquats, limes and even grapefruit are really delicious cured this way.

leahwrenn et al: Sorry, yogurt is so simple it didn't occur to me to actually say how you make it. parudox pretty much covered it above -- the only thing I have to add is that using powdered milk, we usually mix it strong. Like 1.5 times as much milk powder as the box calls for. It seems to come out somewhat thicker that way. Otherwise, we treat it the same as regular milk -- heat to 190 degrees F, cool to 120 degrees F, stir in a little plain yogurt saved from the last batch, and keep it above 90 degrees for 8 hours or so. I have a "Yogotherm" which is just a plastic half gallon bucket and a styrofoam insulating sleeve. It's handy, but you could do the same thing with any number of items you already have around the house (like a small cooler and some warm water, for example). I wouldn't spend any money on anything electric for making yogurt. The bacteria are not that fussy about temperature.

liketitanic: About the cheesecloth thing, I have a cheesecloth that came with an actual cheese making kit. It's fairly tight-woven. Are you using the cheesecloth they sell in like grocery stores, that is more like a loose mesh? It has to be tightly woven enough to contain the yogurt at the start. After it's dripped for a couple hours it gets very thick and almost like a really soft cheese. I bet an old (i.e. kind of threadbare) dishtowel would actually work just as well. Or a piece of an old cotton bedsheet? Anything that water can seep through but yogurt won't will be fine. The whey that comes out is very thin.

A good cheap alternative to a cheesecloth in my experience is a coffee filter. They're a bit finer, but they work.

You can also get cheap, grocery store cheesecloth and double it up a few times (ie 4 to 8 layers).

mine always leaks out through the cheesecloth!!!!! i end up with messy cheesecloth and . . . unfiltered yogurt.

I inherited one of these yogurt cheese funnels (not sure if it's the exact same brand, but mine can open and lay flat when not in use), and it's pretty awesome. Now, the link says this one is no longer in production, but I bet you could get the effect by lining a regular funnel with a couple of layers of cheap, grocery store cheesecloth.

slogger: deadmessenger, do you have any info on how to make Moroccan preserved lemons? This is something that I've been wanting to try.

We do something pretty close to what Keith Talent describes above, although we make cross-shaped cuts in each "pole", don't do the sterilized water (use more lemon juice instead), no refrigeration (refrigerating something that is intended to ferment is counterproductive), and we let it sit out for a minimum of one month, rather than a few days.

Also, to Kaiseki's suggestion, we have a batch of limes preserved in the same way working now - they'll be ready in about 2 weeks or so. I've also done Meyer lemons in this way, and they were quite good. I'll have to try the grapefruit suggestion, that sounds damn interesting.

liketitanic, I use paper towel (two layers) set in a strainer above a deep pan. Then again, I use it to strain yogurt to make yogurt cheese, which is how I can make ranch dip without sour cream and lie to myself that it's healthy.

The thing, though, about fermented food? Who the hell ate it the first time? Who was desperate/hungry enough to open that jar that previously had regular, familiar food, and was presented with the ripe smell of fermented food? Who really thought that eating the first natto would be a good idea? I mean, look at the stuff! Or chou dofu? The fermented black tofu that smells like your own soul dying (and fermenting in a ziploc baggie on the counter in the summer sunlight)? Apples, that I can understand.

I look at fermentation as really being more about time than being about cooking per se. I've made at least two loaves of sourdough every week for about the last maybe 15 years. One thing I can attest to is that starters get better over time. If you want to buy yourself a good one I recommend the one King Arthur sells. It's old and tastes damn good. It's also pretty hearty.

Baking sourdough consistently really requires commitment and a propensity for ritual. You have to always be thinking at least a day ahead. In fact, I don't know of many fermentation products that can be consumed the same day they're started. I kind of like that, but I also kind of dig process.

I believe starters take on attributes from the places where they're cultivated. For example, they taste different in houses where the people don't use alcohol, beer specifically. And I'm sure this sounds suspect but I'm pretty sure there's a difference between starters in homes without a woman and homes with one or more. The thing about wild yeast is it is very much a product of its environment. If you think about it too long it'll skeeve you out. Yeah, you want a little dust in it. It doesn't work without it. And the cultures are these little villages where either the population is healthy and happy, or they aren't, at which point they're not so good for you either.

I've adapted the No-Knead Bread recipe that the Sullivan Street Bakery developed (and which the New York Times and Mark Bittman really publicized) for a sourdough sponge, if you're interested. It's pretty much my go-to bread recipe. Here's my recipe with a video showing you how to make it.

Another way to start a starter is by getting a bit of it from someone who already has it. I also like that social element of this ritual. Besides getting a fresh bit of the wet starter, you can also reconstitute a dried bit of the stuff. I'd be happy to mail you a bit of mine dried if you memail me an address. I'll even send instructions on how to bring it back to life from its suspended animation state. You're success of course will vary. How good are you with goldfish?

Respect to your sourdough skillz, but dude that is some pretty crazy bullshit right there. You're right in that a starter will be soon be replaced by local bacteria from either the air or more likely the specific flour you're using, but beer in the house? Women in the house?? That's the giant reptile overlord of the sourdough world.

All that matter for sourdough is the geography, temperature you keep it at, the hydration, and the grain/s used.

I'm probably letting myself be unduly influenced by lore I've heard from old bakers, and stuff I've read in books on food history, but this is not my idea. And I've also noticed that my bread tasted better when I lived with women. Of course perhaps I was happier when I wasn't alone and that made me better at concentrating and thus a better baker. Not making a scientific claim, about my bread or anyone else's, but I believe lore and oral history needs to be heard. And when you're talking about cooking, seems doing it well is as much about alchemy as it is about science. You don't need to believe it, but you ought to know it's been part of the discussion.

So, yeah, for the record, women are supposed to make sourdough taste better. At least according to my experience and some old bakers I've talked to and read about.

I am loving this thread, this is my humble contribution: The cheap-ass incubator.

You can get yogurt makers with a few ounces capacity for about $15 new, if you want anything bigger the cheap-ass incubator can be made for as little as $5 and some household stuff. It works great, I've used it for sourdough, yogurt, mushrooms, vinegar, kombucha and just to raise bread dough.

Get any more or less insulated container that will hold all your jars, I've used Styrofoam coolers, Rubbermaid containers insulated with cardboard, broken mini fridges and plain old cardboard boxes.

Get a cheap adjustable aquarium heater, you need just a few watts of power, there are some in Amazon for about $5 for non submersibles, $12 for submersibles.

Fill a glass jar with clean water and a few drops of peroxide (to prevent contamination), put the heater in the water, adjust the temperature and cover the whole thing with aluminum foil (to prevent too much evaporation). This will be your heat source, place it in the center of the box and place your jars around it. Top of the water after each use.

The original version used a low wattage light bulb, the aquarium heater makes temperature control a lot easier.

If you want to produce navigable quantities of your fermentables, ask me how to turn a whole bathroom into a clean room/incubator.

For rising bread dough, the more steam the better. Commercial bakery proof boxes are very steamy. Might want to leave the foil off the top of the jar if that's what you're using it for.
