Method
Make it happen
- 01
Rub butter into flour and salt. Add cold water gradually to form a dough, divide into two portions (two-thirds for base) and chill for 25 minutes.
- 02
Roll the larger portion to 3 mm and line a 23 cm deep pie dish, leaving pastry overhanging; roll the remaining dough into a lid.
- 03
Soften the leek in butter for 8 minutes, then stir in flour and cook for 1 minute.
- 04
Slowly add stock and milk, stirring until thick. Mix in cooked chicken, ham and mustard, simmer 3 minutes and leave the filling to cool.
- 05
Heat the oven to 190°C fan. Spoon the cooled filling into the lined dish; cover with the pastry lid, crimp the edges and cut two steam vents.
- 06
Bake for 40 minutes on a preheated tray until the base and lid are crisp and golden. Rest 10 minutes before cutting.
