Acidity In Cooking Quiz – The Power of Sour

Acidity is one of the cook's most important tools. Ingredients like lemon juice, vinegar, wine, yogurt, buttermilk and tomatoes add sourness that brightens flavors, cuts through richness and balances sweetness.

Acid also changes food chemically. Lemon juice slows browning in cut fruit, vinegar helps poached eggs set, buttermilk tenderizes chicken and acidic marinades denature proteins, though fish can turn mushy if marinated too long. Red cabbage turns brighter red with acid.

In baking, acids react with baking soda to release carbon dioxide. Cooks add acid near the end of cooking beans because tomatoes can slow softening. Understanding pH helps explain why a final squeeze of lemon can transform a dish.
