I do it every year. Easy peasy.
The ferment is similar to making sour kraut. Ingredients: chilies, salt, a bit of water, and then vinegar to finish.
Pick your chilies and wash them.
Pulse them in small batches in a food processor. I'll cut off the stem, but you want to chop up the seeds and all. I do this outside, as it can get tough to breath with so much chile aroma in the air.
Once your mash is complete, mix with sea salt. How much? I go by intuition. For a gallon of mash, I'll throw in about half a handful of salt. Mix well.
Pack it into a glass jar or non-reactive crock. I use a two-gallon pickle jar. You want to only fill the jar 50%, leaving a lot of head space for expansion as it begins to ferment. Sometimes if I have a lot of extra mash, rather than starting a second jar, I'll just freeze the extra mash, and then in the weeks ahead, once the fermentation starts to slow down, I'll add extra mash and get it fermenting again. I'll set the jar on a cookie sheet (to catch any over-runs if the mash pushes up over the top of the jar) and leave it on the countertop, out of the sun. I loosely set the lid on top, but don't seal it. If it looks too dry, add some water --- not chlorinated.
Within a couple of days, you'll see it burping and bubbling. It'll push up into the jar, upwards toward the rim of the jar. I like the smell of fermenting chilies—you may or many not. I will use some of the fermenting mash as I cook. If it looks like white mold is forming on the top of the mash, you can add a bit more salt water to cover. I will occasionally give it a stir, at least for the first 3 weeks or so.
Then you leave it. I'll let it go like that for 2 - 3 months. You'll see the mash start to stratify, with chunkier stuff on the top, and the purer hot sauce on the bottom. Eventually, you'll get about one third liquid on the bottom, and two-thirds mash on top. If you want to ferment whole chilies (the way that some people ferment a whole cabbage head when they make kraut), you can wash additional chilis, and submerge them in the bottom of the jar, and then pack the fermented mash back on top of them. It will significantly alter the texture of the chilies if you leave them that way for any length of time. This is fermentation, not pickling. So if you want to ferment a few chilies this way, pay attention and take them out before they start to break down on a cellular level.
Purchase hot sauce bottles on Amazon. You can go glass or plastic. I save $ and go with the larger plastic bottles that hold more. Sterilize them by boiling them in a hot water bath. Sterilize the lids as well as the funnel you'll use and the ladle you'll use to fill the bottles.
Strain the hot sauce by running through a sieve. I'll run the liquid through a series of three different strainers, each one progressively finer. Chili seeds do not break down. Even Tabasco, which ferments their chilies for 2 full years in wooden barrels, finds that the seeds come through the fermentation process whole. The heat comes through and infuses the liquid and the flesh of the chili will disintegrate. But the seeds are tough and don't disappear. I'll take the mash and run it through the food processor again with another cup of water, and then strain the additional good stuff that comes off of it.
You can keep the mash and use it to cook with --- beautiful stuff. I've actually canned small jars of that stuff and given it away. I'll run it through the food pro with a bunch of garlic and it makes a lovely chili paste. It's fantastic with eggs, stir fry, seasoning soups, etc. Hot, garlicy, fermenty, yummy.
Pour the hot sauce into a sauce pan and heat it to a boil. I do this—some people don't. I want to stop the fermentation and kill the bacteria at this point. It helps with preservation. If you want to keep the still active culture alive, more power to you. After boiling for about 10 minutes, I'll add vinegar—I go with plain white vinegar, about a 50/50 ratio. Taste. If it needs additional salt, add it now. Non-iodized salt: I use sea salt. Once it's boiled a few more minutes, it's ready to can.
Bottle. Store. Use.
I don't bother to put the canned bottles into a hot bath (as I do for most other stuff that I can). If you want to be absolutely sure that all bacteria has died, go ahead and do so. For the canned chili paste in jars, I'll boil them back in a water bath for 10 minutes. Because I add so much fresh garlic at the end, I like to give it that additional cook in the water bath.
I've found that my favorite is Serrano chilis. I may throw in whatever other chilis we have growing in the garden, but I like the flavor of Serranos and it's the right amount of heat for me.
I've experimented with the fermentation by adding chunks of apples and persimmons (I make my hot sauce in the fall). I really didn't notice that big of a difference in taste. I suppose it's a way of stretching the chilies a bit farther, but we always have plenty of hot sauce. Garlic can be added to the ferment or added separately after the ferment. You'll get a much stronger garlic taste if it's not fermented. Your call --- go ahead and experiment.
Commercially made hot sauce (like Cholula or Tapatio) has additional thickeners. My sauce obviously doesn't, so it's more watery. I've got no advise if you are looking for that kind of consistency. As it sits in the bottle, you'll see it separate, chilies to the bottom, vinegar to the top. Give the bottle a quick shake before using.
I've kept a quart jar of the fermented chili mash in my fridge for up to a year. It just seems to get better and better with time. If I get a bit of white mold on top, I'll scoop that off the top, and just add a bit of additional salt water to cover the top of the mash.
Best of luck.
