Substitute For Eggs

I saw the query on substitutes for eggs. I had to bake a cake for a little girl a number of years ago who was allergic to eggs, so I had to do some research as to what I could use instead of eggs. I found some info that said to use white vinegar instead. I used 2 teaspoons as I was making an oven pan cake. I was a bit dubious about how it would turn out, but I was quite surprised. The cake was soft and there was no taste of the vinegar. You wouldn't even know that there were no eggs in it.
