Flax egg (ground flax + water)
Classic vegan binding; rest until thickened before combining with dry ingredients.
Fruit adds moisture and natural sugar; flavor and color carry into the finished bake.
Neutral protein and body; blend until completely smooth for even mixing.
Brings tang and liquid; watch total acidity with baking soda or powder in the formula.
Useful for foams and some egg-white roles; whipping behavior depends on concentration and sugar.
Meringues, angel food, and very tender cakes may need purpose-written recipes rather than direct swaps.
3 large eggs → flax egg: about 3 Tbsp meal and 9 Tbsp water (before gelling).
We apply widely published rules of thumb per large egg (about 50 g in shell): 1 Tbsp + 3 Tbsp water for flax or chia gel, ¼ cup for many purées and dairy stand-ins, and ~3 Tbsp aquafaba as a common starting point. Your totals scale linearly with the number of eggs you enter—including halves (e.g., 1.5 eggs worth).
Baking is chemistry in the kitchen: humidity, flour brand, oven, and mix method all matter. Use this tool as a starting point and rely on tested recipes for critical bakes.

You would prepare about 3 Tbsp ground flax and 9 Tbsp water, whisk, and let gel before folding into the batter—then bake per your recipe’s time and doneness cues.
