Some good ideas for egg substitutes for recipes are flax seeds, chickpea flour, chia seeds and bananas. Each of these can be used to replace eggs in any recipe, giving similar results to the final product.
Flax seeds contain an outer layer called epiderm, which is made up of a gel-like substance called mucilage. When used in a recipe, the mucilage in flax seeds works in a very similar manner to eggs. To use flax seeds as an egg replacement in recipes, cooks should buy whole flax seeds, grind them into a meal using a coffee grinder and add water until they assume a gelatinous texture. Chia seeds can be used in a similar way, but do not need to be ground up first, only soaked. Bananas can be added without any processing, but can give the recipe a slight flavor of bananas.
