What it is for

They set the balance. Acid cuts fat, reins in sweetness, denatures protein and triggers leaveners. When a dish tastes like something is missing, it is usually acid rather than salt.

Where it catches you out

Heat drives the aroma out of acid. Squeeze the lemon at the table, not into the pot, and add vinegar at the end.

The knack

Citric acid is not table salt; do not alter the acid amount in a tested canning or pickling recipe.

Storage and health

How to keep it, and who it suits.

Keeping it

Keep in an airtight container in a cool, dry, dark cupboard for 2 years.

Gluten-free

Pure food-grade citric acid contains no gluten grain.
