My third, fourth, and fifth batches of fermented hot sauce:
Two of them started as ways to preserve two bushes worth of green cayennes and Thai chiles (chilis? chilies?) from a back yard raised bed that got a later start in the season so didn’t turn red before the weather turned cool:
I packed a jar full of green chiles with some mustard seed and garlic cloves in a 4% salt brine and let ferment for about a month at 60 degrees, then skimming off mold or anything floating on the surface, straining, tasting, and pureeing with some of the reserved probiotic brine to make a tangy, slightly umami hot sauce (no vinegar added). The cayenne in particular has more going on than just “hot”.
I do want to figure out a better blending / straining technique for the times I want a thin hot sauce that’s less like a chile paste.
