SOAK THE DRIED MUSHROOMS in 200ml of hot vegetable stock for 30 minutes to rehydrate them.
40 g dried mushrooms, 200 ml vegetable stock
MICROWAVE THE CRANBERRIES IN THE PORT for around 1 minute 40 seconds (at 900W), or until the cranberries have soaked up all the port and are nice and juicy. Set aside to cool.
50 g dried cranberries, 50 ml port
CHOP THE MUSHROOMS. Once the dried mushrooms have rehydrated, you’re ready to start cooking your pie filling. Once the dried mushrooms have rehydrated, drain off the liquid (but reserve it, you’ll need it later) and roughly chop them.
FRY. Using a large frying pan (at least 30cm/12"), fry the diced onion, garlic and thyme leaves in olive oil for 3 minutes.
2 tbsp olive oil, 100 g onion, 4 cloves garlic, 3 tsp fresh thyme leaves
Add the rehydrated mushrooms to the pan along with their soaking water, sliced fresh mushrooms and vegan Worcestershire sauce. The fresh mushrooms will release some water whilst cooking; cook until the all of the liquid has evaporated, which will be around 15 minutes on a medium-high heat. Set aside off the heat to cool.
300 g baby mushrooms, 1 tbsp vegan Worcestershire sauce
STIR TOGETHER THE PIE FILLING. Once the fried mushroom mixture has cooled to room temperature, add the port-soaked cranberries, chopped chestnuts and parsley to the pan and stir together. Season to taste.
100 g chestnuts, 2 tbsp fresh parsley
