Jo-Anne, this recipe involves cooking the custard, and then adding the un-cooked blueberries on top. Hope this is what you are looking for.

Blueberry Custard Pie

4 eggs
2/3 cup granulated sugar
1/2 teaspoon salt
1/2 teaspoon nutmeg
2 2/3 cups milk
1 teaspoon vanilla
1 unbaked nine inch pie shell
1 cup blueberries, picked over, rinsed and drained
2 tablespoons orange juice
3 tablespoons confectioners' sugar

Preheat the oven to 425 degrees.

Beat the eggs with a rotary beater until blended thoroughly. Add the granulated sugar, salt, nutmeg, milk and vanilla and stir until smooth. Pour mixture into the pie shell. Bake fifteen minutes; then reduce oven temperature to 350 degrees and bake thirty minutes longer, or until an inserted knife comes out clean. Cool.

Blend the blueberries, orange juice and confectioners' sugar and spoon over custard before serving the pie. Serves 6 to 8.
