Recipe - Golden Onion Quiche

1 8" prebaked quiche shell
7 tablespoon Unsalted butter
2 pound Sliced onions
2 tablespoon Safflower oil
2 tablespoon Flour
3 lg Eggs
1 cup Heavy cream
3 ounce Gruyere cheese; freshly
grated

Preheat the oven to 375=B0. Dice 3 T butter and refrigerate. In a large
saute pan, cook the onions in the remaining butter and oil, starting over
medium heat and gradually reducing to low heat, for about 1 hour, until the
onions are very tender, golden, and reduced considerably in size. Stir
continuously for the last 15 min and be very careful not to let them burn.
They will be extraordinarily sweet and delectable. Discard any burned
parts. Sprinkle the onions w/the flour, using a strainer or sifter, and
saute another 2 or 3 minutes. Beat the eggs and cream in a bowl with a
third of the cheese. Stir in the onions, then pour the mixture into the
quiche shell. Sprinkle with remaining cheese and dot with the minced
butter. Bake 2530 minutes or until browned and set.
