Hot Sauce

Fermentation develops complex flavor—the bacteria and yeast create tanginess, depth, and preservation naturally. Unfermented hot sauce tastes flat and bright; fermented sauce has funky, layered flavor that improves with time. It's also naturally shelf-stable longer.

Skip fermentation and blend the peppers, garlic, and salt immediately, then add 3 tablespoons vinegar and 1 teaspoon sugar instead of 2 tablespoons vinegar. The sauce will be bright and fresh but lacks the complex fermented tang. Refrigerate and use within 4 weeks.

Not keeping the peppers submerged—exposed peppers can mold. Make sure brine covers them by pressing down daily, or place a small glass weight on top. Also, mold (not the white yeast) means failure; white yeast bloom on top is fine and can be stirred back in.

Not really—slow cooking won't create fermented complexity. You can simmer chopped peppers, garlic, vinegar, and salt in a pot for 20 minutes on stovetop for an unfermented sauce, but it won't develop the same depth. Fermentation is the defining step.

Jalapeños give milder, fruity heat; habaneros bring Caribbean fruitiness with serious punch; Scotch bonnets are similar to habaneros; Thai chilies deliver thin, piercing heat. Mix varieties for complexity, or use one type for predictability.

Transfer to sterilized glass bottles and refrigerate. It keeps for 6 months refrigerated and continues to mature slowly. You can also freeze in ice cube trays for individual portions. Unopened, properly fermented sauce can last unrefrigerated for weeks, but refrigeration is safest.
