Chef’s Secret
For perfect meringue or stiff peaks, ensure your bowl and whisk are completely grease-free. A pinch of cream of tartar stabilizes the foam, making it more robust.
Substitutions
Best Match
Aquafaba
3 tbsp : 1 white
Excellent vegan substitute for foaming and binding, good for meringues.
Flax Egg (for binding)
1 tbsp ground flax + 3 tbsp water : 1 white
Primarily for binding in baking, doesn't provide leavening.
Agar-Agar (for thickening)
1 tsp powder : 1 cup liquid
For gelling and thickening, not a direct egg white replacement in most uses.
Silken Tofu (blended, for texture/protein)
1/4 cup : 1 white
Can provide protein and some moisture, but lacks foaming ability.
