hot sauce
A vinegar-based condiment made from chile peppers, ranging from mild and tangy to very hot depending on the pepper variety and brand. Added by the dash for spice and acidity rather than used as a main ingredient.
Buying guidance
Brands vary enormously in both heat and vinegar-to-pepper ratio -- a thin, vinegar-forward sauce behaves very differently from a thick, fruit-forward one, so a 'few dashes' from one bottle won't match another's. Taste a new bottle on its own before adding it to a dish so you know its actual heat level going in.
Substitutions
- Another hot sauce of similar style -- thin, vinegar-based sauces substitute for each other more cleanly than for thick or fruity ones.
- Cayenne pepper plus a splash of vinegar -- rough stand-in when out of bottled sauce; adjust the vinegar to match the tang.
- Red pepper flakes -- adds heat without acidity; fine when the vinegar tang isn't needed.
Tips & common mistakes
Its vinegar tang cooks off faster than its heat does -- capsaicin doesn't break down much with cooking, but the sharp acidity mellows, so a sauce that tasted balanced added early can taste flatter and just plain hot by the time cooking's done. Save a splash to stir in right before serving to bring the brightness back.
Storage
High acidity and capsaicin's natural preservative effect make it one of the more shelf-stable opened condiments -- it's fine at room temperature for a long stretch, though refrigerating is a common habit that helps flavor hold even longer.
