Here’s how I make my quiche :
1 cup plain flour
1 egg yolk
1 tblspn lemon juice.
Rub butter into flour, add egg yolk and enough lemon juice to mix to firm dough.
Refrigerate for 30 mins.
Roll out and place in dish.
Line pastry with greaseproof paper and fill with rice/beans.
Bake in mod hot oven (180C/350F) 10 mins.
Remove paper and rice, bake further 5 mins.
For the filling I use 3-4 eggs, a cup of milk, grated cheese (any combination of cheddar, mozzarella or whatever else I have) and then whatever fillings you like. The kids like ham, tomato and corn (can use canned or frozen) and I usually some dried Italian herbs or fresh basil. You can really put almost anything you like in there though .. Bake for 45 mins at 180C/350F or until starting to brown on top. Serve warm or cold.
