Do My Eggs Need to be at Room Temperature?
Many recipes call for eggs at room temperature. This is because the egg membranes are less viscous at room temperature and mix into the batter more easily. The difference will not be noted in every recipe, but it can make a big difference in egg-heavy cakes such as angel food and sponge cakes. A quick way to bring them to room temperature is to put them in warm water for about 5 minutes.
