I am in the process of turning my family's diet vegan and I have stopped using eggs in my cooking. I have several cheat sheets with ideas for substitutes in baking, etc which I have tried with mixed results. Has anyone tried any commercial subsitute products, what for and do you recommend? In particular, I am no longer able to cook spanish omelette or choux pastry and would love to know if anyone has had any good result with commercial egg substitutes. Thanks!
