Fry bacon until crisp.

Drain the bacon and crumble it into the pie crust.

Arrange Swiss cheese over the crumbled bacon in the crust.

In a bowl, lightly beat eggs with a rotary beater.

Add half and half, salt, pepper, and cayenne pepper to the beaten eggs.

Blend the egg mixture well.

Pour the egg mixture over the bacon and cheese in the pie crust.

Bake in a moderately hot 400°F oven for approximately 40 minutes.

Avoid overbaking the quiche.

Remove the quiche from the oven while the center still appears slightly soft.

Allow the quiche to cool slightly before cutting and serving.
