Here is a recipe I have not made in quite a while but this is a good pie.
*
Edith’s Vinegar Pie
1 stick margarine
1 1/2 cups sugar
2 tablespoons plain flour
1 tablespoon vanilla
2 tablespoons vinegar
3 eggs
1 9-inch unbaked pie shell
Combine ingredients, blending well. Pour into pie shell and bake at 300 degrees for 45 minutes. This recipe came from Edith Grantham of Nichols. She and my mother met back in the 40’s when they were in the Red Cross together. They were lifelong friends.
