When my daughter was pregnant with her first child, she craved this custard. I made this almost every day for her. My grandmother told me that the secret for smooth custard is not to beat the eggs too much; just make sure they are blended well and that there are no pieces of egg floating around the mixture. Also, put a clean dish towel in the bottom of the baking dish that you are placing the custard cups into, and add water to the dish. It don't know what this is supposed to do, but my custard is always smooth and good.
