how much applesauce equals one egg
Many things such as applesauce and a mixture of flax seed will equal out to one egg if you use 1/4 cup of it. Also, a 1/4 cup of an egg substitute will equal a natural egg.
A quarter cup of applesauce is equal to one large egg. Applesauce can also be used as a substitute for oil, in equal quantities.
Applesauce alone won't be enough to substitute for an egg. Add some baking powder. So if you need one egg, you need 1/4 cup applesauce and 1/2 teaspoon baking powder.
