I have so many recipes for different homemade veggie, bean and grain burgers but not one of them calls for egg replacer in the recipe. I find this weird, when ever I make burgers at home and follow the recipe they fall apart so as a result I have started putting egg replacer in them and they are great, so firm and they never fall apart. IS there any reason that recipes do not call for egg replacer, I don't understand it, it makes such abig difference?
