Necro-bumping this thread.
I watched a video on fermenting chilis and making homemade table sauce. I did a batch of red jalapenos and habaneros last week (but didn't document). This week I did a batch of green sauce with jalapenos, serranos, anaheim, tomatillos, and garlic.
First your ferment the chilis, garlic and tomatillos. I did a basic salt-water brine of four tablespoons of pickling salt per half-gallon of water. Cut up the peppers into small pieces, half the tomatillos, and throw in the garlic whole. In this case, after about 4 days of brining the peppers soften up so I added more tomatillos to the brine on day 4. If you don't have a fermenting jar, you have to burp it every day to release the CO2. When you burp the jar it's carbonated, and you can see all of the CO2 bubbles rushing to the surface. You also need to put a weight at the top to make sure all of the vegetables are submerged in the brine. I also did a jar of pickled red onions, but I did that separate because I didn't want to use a whole onion in this sauce, and also wanted to have some on hand for tacos and to garnish other shit.
Let that shit sit in the pantry out of the sunlight for a week. Drain it but reserve some of the brine. Then blend it with the brine and a little white vinegar. I used a cup and a half of the brine and half a cup of white vinegar for this batch. I added a handful of cilantro and juiced three limes.
You can blend it and jar it and throw it right in the fridge at that point, which will slow down the fermentation, but won't stop it so you have to continue to burp the jars. Otherwise you can simmer it over low heat for a few minutes to stop the fermentation, which I did in this case.
After blending and simmering, you can either jar it for a chunkier sauce, or you can strain it through a sieve.
If you want you can save the solids and dehydrate them to make chili flake or a chili crisp that's sorta like dehydrated sea weed. I just threw them away because that sounds like a pain in the ass. I made a big batch so I made one jar of unstrained, and then strained the rest to make almost two jars of a green table sauce.
Walla! Now you've got a shit ton of super spicy and delicious hot sauce.
