Ingredients
3 pounds of fresh peppers (serrano)
1 tsp sourdough starter dissolved in 1/4 cup water
8 cloves garlic (peeled)
60g kosher salt (Diamond Crystal)
< 1/2 cup white wine vinegar (consider other vinegar?)
< 1/4 cup sugar
Directions
Trim and clean peppers, using only good clean peppers
Working in 2 batches, pulse pepper, garlic, and salt in food processor until mixture is finely ground
Transfer mixture into large bowl
Stir sourdough starter mixture and 3 tablespoons of vinegar into pepper mixture
Spoon mash into 2 sterilized large mouth mason jars and stir to remove air pockets
Screw on lid with brewers airlock
Place jars in a tub (in case of overflow) and store in a dark place at room temperature for 12-16 days
Check periodically
Squeeze mash through mesh bag and strainer (wear gloves) extracting about 3-1/2 cups of strained liquid
Whisk remaining vinegar and sugar into strained liquid until combined
A little Xanthan gum (~1/4 tsp?) will work as an emulsifier to keep the sauce from separating
Transfer hot sauce into small bottles and store in refrigerator for use
