I'm trying to reduce cholesterol in my diet and have switched to using egg whites (from a carton) instead of whole eggs. This substitution usually works out OK, but when I make zucchini bread -- and other quick breads -- the loaves don't rise as well as they used to, and they tend to be drier.
I'm doing a 1:1 substitution using the guide on the carton (1egg is approx. 2oz), so I assume that a lot of the problem is that I'm missing the fat from the egg yolks. Is this correct, and if so, what can I use instead that will be low in cholesterol?
