Use One Egg At a Time
It can be tempting to cut corners when baking and add all of your eggs at the same time. However, baking requires patience and following directions. If your recipe calls for them to be added one at a time, that is exactly what you should do. If there’s nothing specified, you may add them at the same time for good results.
Adding them one at a time will make a big difference for most desserts. It can mean the difference between a flat cheesecake or a fluffy meringue. A good rule of thumb is to always add them in one at a time even if the recipe doesn’t call for it.
