Little Note re Vegan Egg Substitutes
Most “egg substitutes” only work well for a specific use case of eggs, and not for others. E.g:
Aquafaba (chick pea water) whips up like egg whites and can be used to make sponge cakes, merengues or similar fluffy sweets.
Chia or flaxseed/linseed are a good replacement binder for muffins and denser cakes (and good for fibre and protein too).
Tapioca starch and baking powder can also work to give a bit of leavening for muffins (McKensie brand vegan baking egg subtitute is this).
Ground cashews and/or avocado can be used for some richer desserts like mousses.
Kala Namak, a dark sulphurous salt which adds the smell and flavour of egg yolk, but doesn’t add texture like the above stuff.
Tumeric is often used to add a bit of yellow colour to make vegan omelettes and scrambles look like eggs.
I haven’t yet seen any subsitutes that are a straight drop in for all purposes of eggs, usually you have to use several depending on the recipe.
