Method: for the filling:
1. Remove the white cores (our dogs love this bit) from the kidneys and chop into 2 cm cubes.
2. Cut the fat and gristle from the beef and chop into 2 cm chunks.
3. Toss the beef and kidneys in the flour to coat
4. Heat 2 tbsp of oil in a large saucepan in a large heavy based saucepan or casserole (with a lid) and in batches, quickly brown the meat well over a medium heat. Stir every now and then so the meat doesn�t stick. Set aside when browned in a warm place.
5. Add the remaining 2 tbsp of oil to the saucepan and add the onions. Stir well to insure that they are covered with the oil. Cook over a low heat for five minutes, covered.
6. Add the carrots. Stir to cover with the juices and leave for two minutes.
7. Add the meat and the stock. Stir well and increase to heat to medium.
8. Bring to simmering point and add the balsamic vinegar, thyme, and porcini mushrooms and their juice. Add the Lea and Perrins, mushroom ketchup, juniper berries and peppercorns. Stir well.
9. Simmer gently (lid on) for an hour and a half. Depending on the quality of the steak, the meat may be tender after an hour. So set a timer and check. This is generally a good idea as after an hour you have given the meat long enough to develop its flavour and you can make adjustments if necessary.
10. Towards the end of the cooking time add the portobellini mushrooms and simmer gently for 20 minutes (a decent stew will benefit from resting overnight. We often pre cook the filling for our pie the day before it is needed. Then we add the mushrooms the next day when we heat the mixture before adding the pastry and baking the pie).
11. Whilst the mushrooms are cooking add a little of the gravy (liquid from the stew) to the potato flour to make a wet paste (no lumps) and stir it this into the stew. Simmer for a few minutes until the sauce has thickened. Check for seasoning
