Flaxseed Meal (Best Option)
1 tablespoon flaxseed meal + 3 tablespoons water per eggFlaxseed meal mixed with water forms a mucilaginous gel that mimics the binding and moisture-retention properties of eggs, essential for doughnut dough elasticity and structure. This gel helps trap air bubbles during frying, contributing to a light texture.
For best results, allow the flaxseed mixture to sit for 5-10 minutes to thicken before incorporating it into the dough. Avoid using too much flaxseed as it can impart a strong flavor and make the dough heavier.
Compared to eggs, flaxseed meal slightly alters the flavor profile with a mild nuttiness but maintains a similar texture and moisture balance, resulting in doughnuts that are tender and well-structured.
