With butter use 1 1/2 cups milk. With vegetable shortening use 2 cups. Measure sifted flour. Add baking powder and salt, sift together three times. Beat egg whites until frothy. Add 1/2 cup sugar gradually and continue beating until meringue will hold up stiff peaks. Cream shortening; add 2 cups of sugar gradually and cream together until light and fluffy. Add flour mixture, alternate with milk a small amount at a time, beating after each addition until smooth. Add vanilla, then add meringue and beat thoroughly into batter.

Pour batter into three round 9 inch layer pans which have been lined on the bottoms with paper. Bake in moderate oven, 350 degrees, for 25 to 35 minutes. Cool layers; spread two layers with Lemon Filling. Put together and cover top and sides the fluffy Seven Minute Frosting. While frosting is still soft, sprinkle with coconut.

LEMON FILLING:

3/4 c. sugar
1/4 c. cornstarch
1/4 tsp. salt
1 c. water
2 egg yolks, slightly beaten
1 tsp. grated lemon rind
1/3 c. lemon juice
1 tbsp. butter

Combine sugar, cornstarch and salt in top of double boiler. Blend together egg yolks, water and lemon juice in small bowl. Add to sugar mixture gradually blending well. Cook over boiling water about 5 minutes or until mixture thickens, stirring constantly. Remove from heat; add butter and lemon rind. Cool slightly before spreading over cake.

SEVEN MINUTE FROSTING:

2 egg whites, unbeaten
1 1/2 c. sugar
Dash of salt
1/3 c. water
2 tsp. light corn syrup
1 tsp. vanilla

Combine egg whites, sugar, salt, water and corn syrup in top of double boiler. Beat about 1 minutes or until mixed well, then place over double boiler and boil and beat constantly with a sturdy egg beater or at high speed of electric mixer for seven minutes or until frosting will stand in stiff peaks. Stir frosting up from bottom and sides of pan occasionally with a rubber spatula. Remove from boiling water for a very smooth and satiny frosting. Pour at once into a large bowl for a final beating. Then add vanilla and beat 1 minute or until thick enough to spread.
