This is a great quiche! The only thing I did different was add 3/4 tsp wostershire sauce and mix all the ingredients together instead of building in layers. I had to cook for about 45 minutes and cut into it too soon(couldn't wait!)You can alos substitute gruyere with Swiss cheese. Quiches, since they are basically a savory custard should set like a custard(at least 1 hr). The taste is unbeatable. Thanks for posting!
