Regular Custard
Unbaked Pie crust
Berries (enough to cover bottom of pan - at least a cup)
Sugar
Flour

Make a regular custard. Put the berries in crust to cover the bottom, at least a cup. Some berries take more sugar than others, just guess. Sprinkle 1/4 cup more sugar over them. Pour the custard over the berries. If you are using a juicy berry like blackberry, either stir a teaspoon of flour into the sugar or use a little less milk in the custard. Don't bake custard in as hot an oven as other pie.
