Here is a flavorful and much lighter alternative.
2 cups French bread cubes (cut off crusts)
3/4 cup sugar
The juice and zest of one lemon
1/2 cup melted butter
4 eggs, separated
2/3 cup milk
Combine bread cubes, sugar, lemon juice, and zest; stir well. Add butter and stir to blend.
In another bowl, beat the egg yolks until thick and lemon colored. Add the milk. Pour over the bread mixture.
Beat the egg whites until stiff peaks form. Fold them into the bread mixture. Pour all into a buttered 1 - 1/2 quart casserole. Bake at 350° for 30 minutes.
Serve warm with Lemon Sauce (below).
1/2 cup sugar
1 cup hot water
1 tbl. cornstarch
2 tsp. butter
1 - 1/2 tbl. lemon juice
dash of nutmeg
pinch of salt
Mix and cook in double boiler (or in microwave) until smooth and thick. Cool slightly before serving.
