A pinch of cream of tartar stabilizes egg white foam, allowing it to reach higher volumes and remain stable longer, crucial for perfect meringues.
Substitutions
Aquafaba (Chickpea Brine)
Excellent vegan substitute for foaming properties in meringues, mousses, and cocktails.
Flax Egg
Good binder in baking, but lacks aeration properties of egg whites; not for meringues.
Powdered Egg White
Convenient, shelf-stable, and performs well for whipping and baking, often used by professionals.
Silken Tofu (blended)
Acts as a binder and emulsifier in savory dishes and some baked goods, not for aeration.
Buying Guide
Opt for fresh, liquid egg whites in cartons for convenience, or separate from whole eggs. Check expiry dates.
