Here are two recipes for boiled custard similar to my mother's. http://food4.epicurious.com/HyperNews/get/...s/15/4/1/7.html http://www.cooks.com/rec/doc/0,1640,147177-227202,00.html It isn't really boiled, but cooked in a double boiler. I guess the name is meant to differentiate it from a baked custard. My mother heats the milk first, then beats the eggs , then tempers the beaten eggs with a little hot milk. The egg-milk mixture is slowly added to the remaining milk, then the sugar, salt, and vanilla are added. The custard is done when it coats the back of a spoon. Refrigerate then serve(in small glasses, it is very rich).
