Theses photos are from last summer when the farmers market had red habaneros. They are usually only available July, maybe August from local grown sources. If you can't find these or don't want it fiery hot use fresno chilies or you can use any red chile.
1lb red Habs, snip off stems but leave the green shoulders. It add some depth to the flavor. Hard to explain what but there is a taste difference if they are removed.
The puree should be thick enough to hang on the spoon.
Pour into a mason jar and screw on lid tight. Or you can use a burping valve. Let ferment for 1-4wks depending on the tang you like. Start tasting after 2wks. I have tried an unfermented version using vinegar and prefer the fermented. The fermenting process changes the flavor and texture for the better, and you do not need to add vinegar to get the desired sourness.
When fermentation is complete you can use as is for the probiotics or you can cook. Either way add 2tbsp coconut sugar and mix thoroughly. Add more salt if needed. I've made both raw and cooked, the latter has better flavor and texture
Put into clean jar and store in the fridge. Hab sriracha is way hot compared to fresno's and Thai chilies are some where in between. There's no comparison to the store bought version, the depth of flavor here is incredible!
One concoction I made used the Trinidad scorpion butch T peppers. This sauce is so freakin' hot just tasting the tip of the spoon sent me reeling. I made 5 batches last summer to hold me over till the next season.
