Warm Onion Pie

This is so good and another nod to the "Ivy" in Fort Madison up the road from Nauvoo.

1 stick butter, divided
1 cup breadcrumbs
1 teaspoon salt
3 cups diced sweet onions
1 Tablespoons flour
2 cups finely grated Swiss cheese
1 teaspoon salt
1/4 teaspoon cayenne
1 cup scalded milk
3 eggs, well beaten

   Melt half the butter and mix with breadcrumbs and salt.  Place in a well-greased 8-inch pie pan, and press into bottom and up the sides.
   Saute onions in remaining butter slowly, stirring constantly until onions are clear and tender.  Remove from heat.  Drain onions and place over crust.
   Combine flour, cheese, salt, and cayenne pepper.  Scald milk, add eggs, and stir.  Add milk mixture to cheese mixture.  Carefully pour batter over onions.  Bake at 350 for approximately 30 minutes, or until golden brown.  Makes 6 to 8 servings.
