Preheat the oven to 180°C/350°F/Gas 4.
Heat the butter and rapeseed oil in a large frying pan, add the onion mushrooms and cook over a low heat for 2-3 minutes or until soft. Then stir in the cooked turkey, garlic and thyme and cook for a further 3 minutes, pour over the brandy and allow to bubble for 1 minute, then add the stock and cream and warm through gently. Remove from the heat and stir in the stilton, season with sea salt and black pepper.
Divide the turkey mixture between 4 individual pie dishes.
Unroll the pastry and cut into four pastry lids (slightly larger than the individual pie dishes). Then wet the rim of the dishes with water. Lay the pastry circles over the top and press to the rim firmly. Make a small slit with a knife to allow the steam to escape. Brush with beaten egg and place on a baking sheet and bake for 20 minutes until golden.
