Try to bring eggs to room temperature when possible. Place on counter 30-60 minutes before you bake. If you forgot then place eggs in a bowl of warm water for 5-10 minutes. Use large eggs in most recipes – or what is specified. When you add sugar to eggs or especially egg yolks, you need to mix the two ingredients because the sugar can “burn” the yolk when just sitting on it for a while. When you crack an egg – crack it on the counter and not the side of the bowl to better avoid (little pieces of) shell breakage and shells in your dessert.
