The 12 egg cake involves:
1 lb butter, well creamed (salted is fine, it usually has fewer ingredients anyway)
4 Cups sugar, creamed again
12 eggs, added 1 at a time, continue creaming
4 Cups flour, mixed in
And flavoring (lemon, vanilla, almond, whateves)
There are various techniques for adding the flour, and some people add a nib of salt or baking powder/soda ... none of which I've tried. I like the simplicity of just the 4 basic ingredients plus vanilla bean or lemon zest. But I've never made this cake. I'm not feeling that suicidal.
Then it fills *2* ten inch tube/bundt pans! Greased, etc., don't overfill as it poofs while baking.
Glaze if all of the above somehow isn't enough.
OK so I am assuming you dont do Baking powder or soda with this cake? and are dependant on the eggs to keep it fluffy?
The egg custard is a quantity of milk, heated but not boiled, mixed with a quantity of well beaten but not whipped egg, not as much sugar as you'd think, smidge of salt as always, baked in a hot-water bath until not quite set. I'll add vanilla bean while heating the milk. Nutmeg on top if you wish, or crunchy bakers sugar. Or both. I'll have to check an actual recipe for exact ratios, but big eggs always add chaos to measurements. As does my flakey oven. This is FABULOUS if you arrange peach halves in the baking dish before pouring in the eggs. You can do individual ramikins if you're fancy. And fancy cooks also like to strain it before pouring. Meh. Serve warm or chilled. So simple, so yum!
OK Now I want a duck.... um er ducks. I am really liking Runner ducks...
