Joy of Cooking Yorkshire Pudding

Sift together:
7/8 cup flour
1/2 tsp. salt
Make a well in the center, in which you pour
1/2 cup milk
Stir in the milk.
Beat until fluffy:
2 eggs
Beat them in the batter and add:
1/2 cup water.

Preheat oven to 400 degrees.

Beat the batter well until large bubbles rise to the surface. You may permit this to stand covered and refrigerated for 1 hour and then beat again. Have ready a hot ovenproof dish about 9x12, or hot muffin tins containing about 1/4 inch hot beef drippings or melted butter. Pour in the batter. It should be about 5/8 inch high.

Bake the pudding about 20 minutes. Reduce the heat to 350 degrees and bake it 10 to 15 minutes longer. Some cooks recommend a 350 degree oven for 1/2 hour or longer.
Serve at once.
