Wish I had read Matmob's review before making this quiche! I also used GF flour and it made a paste. Pushed it in a tin, froze it for an hour, and put it in the oven. Horrified to see the pastry slide down the tin's edges and be bubbling in the bottom of the tin..
Cooked the ruined pastry and when I took it out, realised it was the making of a great crumble for a topping
Made a different base, and then found I didn't think there was enough cream and egg mix for the size of the quiche. So added more egg and cream. After all of this, the quiche was very nice, just very late
