a 13 egg custard pie recipe?

Question

this recipe is a very old recipe that my grandmother use to make. She never wrote it down and so no one knows how to make it

Answer 1

Grandma's Egg Custard Pie
Makes one 9-inch pie

This is the 1999 American Pie Council's National Pie Championship's
first place winner in the Custard Pie Category.

Ingredients

1 (9 inch) unbaked pie crust
3 large eggs, room temperature, beaten
3/4 cup white sugar
1/4 teaspoon salt
1 teaspoon vanilla extract
1 egg white
2-1/2 cups scalded milk
1/4 teaspoon ground nutmeg
3 drops yellow food coloring (optional)

Directions

1. Preheat oven to 400 degrees F (205 degrees C).
2. Mix together eggs, sugar, salt and vanilla. Stir well. Blend in the
scalded milk. For more yellow color, add few drops yellow food
coloring.
3. Line pie pan with pastry and brush inside bottom and sides of
shell with egg white to help prevent a soggy crust. Pour custard
mixture into pie crust. Sprinkle with nutmeg.
4. Bake for 30 to 35 minutes or until a knife inserted near center
comes out clean. Cool on rack {COULD NOT FIND a 13 egg custard, but this sounds like the one my grandmother yused to make.}
