1/4 c. butter
1/4 c. flour
1/4 tsp. salt
1/8 tsp. pepper
1 c. milk
4 eggs, separated
1 c. finely chopped asparagus, cooked, well drained

With butter, flour, and milk, make a smooth gravy. Remove from heat and add egg yolks, blend. Stir in asparagus. Beat egg whites until stiff; carefully fold into mixture. Bake in a greased 2-quart baking dish (straight sided) in preheated oven 30-40 minutes at 375 degrees, or until puffed and knife inserted will come out clean. Serve at once. Makes 4 servings. Other vegetables may be substituted for the asparagus.
