Chicken and Leek Pie with Creme Fraiche & Mustard (www.krumpli.co.uk)

Chicken and leek pie with a wholegrain mustard, white wine and creme fraiche sauce topped with a golden puff pastry lid in individual pots.

Cooking this dish takes a while but the filling can be made days in advance and chilled or frozen. All you then need to do is add a lid and bake in the oven!
