- You can spend more time with your guests instead of being stuck in the kitchen.
Mary Berry Christmas Game Casserole (serves 8)
Ingredients
Vary the proportion of meats as you like, and, if you have difficulty getting the exact amounts of mixed game, you can make up the difference with braising beef or Boneless chicken. In season, some supermarkets sell packs of mixed game – often including venison, pheasant, rabbit, wild duck and pigeon.
1.4kg (3lb) mixed game meats (see above)
2 tablespoons sunflower oil
75g (3oz) butter
200g (7oz) smoked bacon lardons
450g (1lb) whole frozen chestnuts, thawed
4 leeks, thickly sliced on the diagonal
50g (2oz) plain flour
300ml (½ pint) red wine
600ml (1 pint) chicken stock
4 tablespoons redcurrant jelly
salt and freshly ground black pepper
1 large orange
To Serve
2 tablespoons chopped fresh parsley
1 orange, sliced
Method
- Trim the meats and cut into 5cm (2in) pieces.
- Heat the oil and half of the butter in a large non-stick frying pan or casserole. Brown the game and bacon over high heat in batches. Remove with a slotted spoon and set aside.
- Add remaining butter and brown the chestnuts. Remove with a slotted spoon and set aside. Add leeks and fry briefly over a hot heat.
- Sprinkle in the flour, gradually blend in red wine, stock and redcurrant jelly. Bring to the boil, season with salt and pepper then add the whole orange and meats.
- Cover and cook over low heat for 1½–2¼ hours (or in a 160°C / 140°C fan / Gas 3 oven for similar time) until meats are tender. Check halfway and add stock if needed. (You could also cook the casserole in the oven preheated to 160°C/Fan 140°C/Gas 3 for about the same time.)
- About 15 minutes before finishing, add chestnuts.
- Once the game is tender, lift the softened orange into a sieve, cut in half, stand over a bowl and push the orange through the sieve, collecting the juice. Gradually stir the juice into the casserole until the taste is perfect. Check the seasoning and add a little more stock if the casserole is still a little thick.
- Garnish with freshly chopped parsley and orange slices. Serve with your choice of sides.
