Ingredients
Method
- Put the flour, salt and cold butter in a bowl. Rub the butter in with your fingertips until it looks like coarse crumbs with a few pea-sized pieces left.
- Add the egg yolk and 2 tablespoons of ice water. Bring together with a fork, adding more water a spoon at a time only if it won't hold. Stop as soon as it forms a dough — don't knead.
- Flatten into a disc, wrap, and chill for 30 minutes.
- Roll the dough to about 3 mm (⅛ inch) on a floured surface and line the tin. Press into the corners, trim the edge, and prick the base all over with a fork. Keep cold while the oven heats.
- Preheat the oven to 190 °C / 375 °F. Line the shell with baking paper, fill with baking weights and bake for 15 minutes.
- Remove the paper and weights and bake for another 8–10 minutes, until the base is dry and pale gold. Lower the oven to 180 °C / 350 °F.
- Fry the bacon in a dry pan over medium heat until crisp. Lift out with a slotted spoon, leaving the fat in the pan.
- Fry the onion in the bacon fat until soft and golden, about 8 minutes. Set aside with the bacon.
- Whisk the eggs, cream, milk, a pinch of salt and plenty of pepper in a jug. Stir in most of the Gruyère and the chives, keeping a small handful of cheese for the top.
- Scatter the bacon and onion evenly over the base of the shell.
- Pour the custard over and sprinkle the remaining cheese on top.
- Bake at 180 °C / 350 °F for 35–40 minutes, until the top is golden and the center is set with a slight wobble.
- Rest for at least 15 minutes before slicing.
Notes
Seal the base: brush the hot blind-baked shell with a little beaten egg white and return to the oven for 2 minutes. No soggy bottom.
5 eggs or 4: five eggs gives a firmer custard that slices cleanly and holds cold. For a softer, more custardy quiche, use four and pull it a few minutes earlier.
Don't skip the rest: slicing straight from the oven gives a runny middle. Fifteen minutes on the counter and it firms up.
No need to freeze the shell before blind baking — as long as the dough goes in cold and isn't stretched when lining the tin, it holds its shape.
Storage: keeps 3 days in the fridge, covered. Reheat slices at 160 °C / 320 °F for 10 minutes, or eat cold. Freezes well — cool completely, wrap slices individually, reheat from frozen at 160 °C / 320 °F for 20–25 minutes.
