Fermented hot sauce is basically your chiles of choice with garlic, onion, carrots or even fruit. The contents are left to ferment in a salt brine for a few weeks and then blended with the leftover brine and also vinegar. The vinegar slows the fermentation down if you’re storing in the fridge. The sauce can be cooked for a few minutes to kill fermentation if you plan on bottling the product.
Check out ATX hot sauce on youtube for an idea of what it is. Also if you could tolerate Reddit, there’s a r/hotsaucerecipes page where people post up their recipes.
I plan on making some once my birds eye chilis come in.
Let me ask you this, what’s your plans for the Hatch? Surely you must have a plan if you ordered 10bs of them? Lol
