Egg Substitution Guide

Why Eggs Are Hard to Replace?

Eggs perform multiple functions in baking: binding (holding ingredients together — proteins denature and set). Leavening (trapped air from beating, plus CO2 from reaction with leavening agents). Moisture (eggs are approximately 75% water). Emulsification (lecithin in yolks emulsifies fat and water). Structure (proteins provide structural support in cakes and custards). Colour and flavour. No single substitute replicates all functions — choose based on the primary role eggs play in your specific

What's the key thing to understand about Best Substitutes by Function?

For binding (cookies, brownies): flax egg (1 tbsp ground flax + 3 tbsp water, rest 5 min), chia egg (1 tbsp chia seeds + 3 tbsp water), banana (¼ cup mashed per egg). For leavening (cakes, muffins): aquafaba beaten (3 tbsp per egg), commercial egg replacer, 1 tbsp vinegar + baking powder combination. For moisture: applesauce (¼ cup per egg), yoghurt (¼ cup), silken tofu blended (¼ cup). For emulsification (creamy textures): silken tofu blended (¼ cup), commercial products (JUST Egg). For meringue and whipped textures specifically, aquafaba (chickpea water) is the only substitute that genuinely replicates egg white's whipping properties.

What should I know about Flax and Chia Eggs?

Flax egg: 1 tablespoon ground flaxseed + 3 tablespoons water. Mix and rest 5-10 minutes until gel forms. Provides: binding, some moisture. Works best in: dense baked goods (brownies, cookies, dense cakes). Imparts slight nutty flavour. Does not provide leavening. Chia egg: 1 tablespoon chia seeds + 3 tablespoons water. Rest 5-15 minutes. Similar to flax egg in function. Slightly firmer gel. Can be whole seeds (add texture) or ground (more neutral). Both are excellent for vegan and allergy baking where a binding function is needed, though they add a mild nutty flavour that works better in denser bakes like muffins and quick breads than in delicate cakes.

What should I know about Aquafaba?

Aquafaba (chickpea water): the brine from a can of chickpeas. 3 tablespoons per egg, or 2 tablespoons per egg white. Can be whipped to stiff peaks like egg whites — the breakthrough discovery for vegan baking (2014). Used for: meringues, macarons, angel food cake, mousse, mayo, aioli. Flavour: very mild — essentially neutral when baked. Recipes using aquafaba: vegan meringue cookies (equal parts aquafaba and caster sugar). Vegan chocolate mousse. Aquafaba fails at: yolk functions like emulsification and richness, so it's not a good substitute in recipes that rely primarily on yolks, like custard or mayonnaise.
