Beat the eggs, add the cream and half and half. Mix well. Add to unbaked pie shell with any filling you want. It's sometimes easier to season the ingredients in the pie shell then add batter as then the seasonings won't settle to the bottom of the batter. Bake quiche in a preheated 375 degree oven for approx 30 to 45 minutes or until filling is set. Baking time depends on size of pie shell. Smaller 6 inch pies will bake in approx. 30 minutes. Larger fluted edge tart pans will take approx 45 minutes or so.
