1/4 cup butter
Place in a pie plate or 8" baking dish and put in oven to melt while preheating oven to 350 degrees.
In a blender mix:
3/4 cup milk
3/4 cup flour (wheat works, but unbleached white is nicer!)
Blend well and pour into heated dish with melted butter.
Bake at 350 for 20-25 minutes till puffed and lightly browned.
Serve immediately, it will "puff down" quickly, so this is one to get right on the table :-)
For a little variation, you can add 1/2 cup cooked apples and a tsp of cinnamon to the baking dish before pouring egg mixture on top. Very yummy!
