Dietary Substitutes

Replacing animal products is mostly a question of function. Work out whether the original ingredient was binding, adding fat, adding lift or adding moisture, then replace that job rather than the ingredient.

Dairy does three different jobs in cooking — fat, water and acid — and rarely all three at once. The right swap depends on which one the recipe is relying on.

Gluten provides structure and elasticity. Gluten-free swaps almost always need a binder alongside the flour, which is why a straight one-for-one exchange usually disappoints.

Sugar is not only sweetness — it is moisture, browning and tenderness. Swaps that match the sweetness rarely match the other three, so expect to adjust.

Swaps for the most frequently avoided allergens. Always check the label — manufacturing processes and formulations change, and cross-contamination varies by brand.
