This is a dense cake even with the angel food tag. The custard you put on the top is a very nice compliment to the cake. We did use this recipe for Tessa's wedding cake but it didn't stand up the decorations too good....but most people enjoyed the cake even tho it wasn't the most beautiful wedding cake. The top layer slipped off. I'm not a very good cake decorator.
First mix the sugar and flour together. Then add the boiling water. Let this cool. Then add the salt, baking powder, cream of tartar, & salt. Beat the egg whites stiff and add 1/2 cup of sugar. Now fold the cake batter and the egg whites together.
Bake about 45 min. in an extra long loaf pan. I've also baked this in an angel food cake pan, a bunt pan or a layer cake pan.
Custard topping.....Mix egg yolks in a small bowl with sugar and flour. Heat the milk. Remove 1/2 c and mix with the egg yolks. Then add this to the pan of milk and cook until thick. Stirring constantly. Serve the cake with a spoonful of this over it and some fresh fruit sprinkled on the top.
