Tips

Tip 1

Work quickly with the pie crust in a cool environment, and freeze for 5 minutes if it becomes unmanageable during rolling or shaping.

Tip 2

The center should remain slightly jiggly when done - it will continue cooking from residual heat and firm up as it cools.

Tip 3

Transfer the filled quiche on a baking tray to prevent spills when pouring the custard mixture directly in the oven.
