Shoutout to my friend in Boise who finally got me to try fermenting peppers without vinegar. I thought it was just for pickles. | Fermentation Station - Free To Speak
Listen to the_fiona, she's right. Skip the vinegar and use a 3% salt brine by weight. Let it sit for two weeks, burp the jar daily, then blend it with some of the brine. That's your base.
Remember my buddy who tried making hot sauce with vinegar? It came out tasting like spicy salad dressing, totally flat. He switched to a salt brine ferment like you said and it was a game changer. That funky depth is everything.
