Aunt's recipe
halved
Ingredients:
Concord Grape Pie (loosely) 4 cups grapes off stems 3/4 cups sugar or to taste 3 T cornstarch pinch salt 1 T butter
Pinch pulp out of grape skins. Save skins. Put pulp in saucepan. Simmer until they are soft enough to put through food mill or strainer (with all liquid) to remove the seeds. You should have 1 1/4 c pulp. If not, add water. Add the cornstarch, sugar and skins and mix well. Pour into pie shell. Top with second crust. Slash crust and bake at 425 for about 50 minutes or until filling bubbles out of the crust.
