Lemon Pudding Cake Recipe

In a bowl, beat egg yolk. Add sugar, milk, flour, lemon juice, peel and salt; beat until smooth. Beat egg white until stiff peaks form; gently fold into lemon mixture. Pour into two ungreased 6-oz. custard cups (cups will be very full). Place the cups in an 8-in. square baking pan. Pour boiling water into pan to a depth of 1 in. Bake at 325° for 40-45 minutes or until a knife inserted near the center comes out clean and top is golden. Serve with whipped cream if desired. Yield: 2 servings.
