Sift the flour and rub it with butter and salt into crumbs. Add water and quickly knead the dough. Wrap in film and refrigerate for 30 minutes.
Roll out the finished dough into a layer 4-6 mm thick and distribute it over the pan, cutting off excess edges. Bake under a weight at 180-200 °C for 7-10 minutes.
Fry the ham and pat dry with paper towels to remove excess fat.
Whisk eggs, cream, milk and salt until smooth. Spread the ham into the quiche base and pour in the egg mixture. Bake at the same temperature for 20-25 minutes.
