I make my mother's custard often. It is so easy. It's 2 C milk, 3 eggs, 1tsp vanilla, 2T sugar, pinch of salt, nutmeg or other spice to taste (I shake some pumpkin pie spice in). Mix with a hand egg beater until mixed. Pour in a bowl. Put bowl in pan with water in it. Bake 325 degrees for about an hour or until knife comes out clean in center. I usually double the batch and make it in two bowls.
