What does substituting an egg for shortening in pancakes do?

Substituting an egg for shortening in pancakes alters the texture and moisture content of the batter. Eggs provide structure, richness, and binding, which can lead to a fluffier and more tender pancake. In contrast, shortening adds fat, contributing to a moist and rich flavor. This substitution may result in a slightly different taste and texture, but pancakes can still be delicious.
