Instructions: Start heating oven to 375 F. Pour boiling water over beef; let stand one minute; then drain or use beef right from package or jar if you prefer a full flavor.

Melt butter in large skillet or saucepan. Heat dried beef in butter, stirring, until slightly crisp. Stir in flour, pepper. Add milk; cook, stirring, until smooth and thickened. Add pimento, drained mushrooms. Pour into 1 1/2 qt. casserole. Put casserole into oven.

Then make this topping: Add salt to egg whites; beat till stiff. With same beater, beat egg yolks till light-colored; then fold into beaten whites.

Pour over hot creamed dried-beef mixture. Bake, uncovered, 20 to 25 minutes, or until cake tester or toothpick inserted in topping comes out clean.

Serve at once from casserole.
