2 tablespoon butter or margarine
3/4 cup sugar
3 eggs, separated
1/4 cup all-purpose flour
3/4 cup water
1/4 cup cider vinegar
1 tablespoon vanilla
salt
pastry for 1 pie shell
Stir or beat butter to soften (do not melt); add sugar and beat until well mixed. Beat in egg yolks until light; add flour, beating until all flour is mixed in. Combine water, vinegar and vanilla; add about 1/4 cup to egg yolk mixture, stirring until well mixed. Stir in the remaining water mixture.
Beat the egg whites with a dash of salt until stiff peaks form. Fold 1/4 of the whites into yolk mixture to lighten. Gently fold in remaining whites. Pour mixture into an 8 or 9 inch unbaked pie shell. Bake pie in 425 deg F oven for 10 minutes. Reduce heat to 350 deg F and bake 30 minutes. Cool completely before cutting. Sprinkle with confectioners’ sugar, if desired.
Makes 6 to 8 servings.
