Acid: The Ingredient You Forget

When a dish tastes flat but not undersalted, it is almost always missing a squeeze of something bright.

Cooks reach for salt when a dish tastes flat, and often salt is not the answer. A squeeze of lemon, a splash of vinegar, a spoon of yogurt: acid lifts and focuses everything else on the plate.

Keep a few acids in rotation. Lemons and limes for brightness, red wine and sherry vinegar for depth, rice vinegar for a gentler lift. A rich stew wants a different acid than a delicate salad.

Add it at the end and taste. Acid fades with heat, so a braise that had plenty of wine at the start still often wants a fresh hit of vinegar just before serving.
