Steak and kidney pie, crock pot version

Once again we were very fortunate to be given some more fine food. This time, fresh kidneys and some liver courtesy of hubby's workmate Bruce, who had recently had a steer butchered. So steak and kidney pie was on the menu.
I found a good recipe for a crock pot version of cooking the steak and kidney, then just make some short crust pastry for the actual pie.

Ingredients:

Some Stewing beef about 500 or 600g
Kidneys or just one chopped up beef kidney, it was quite large
3 Carrots, peeled and chopped
2 onions, chopped
A good slug of Worcestershire sauce
A small dash of Balsamic vinegar
About 8 juniper berries
About 8 whole black peppercorns
A squirt of tomato ketchup
A small handful of dried shitake mushrooms, soaked in hot water (add some of this liquid to the stew)
A handful of fresh thyme, chopped
Enough stock to almost cover the contents of the crock pot

Preheat crock pot and spray with oil. Chop up the beef and kidney into bite size pieces. Toss in flour to coat. Add to crock pot. Add carrots and onions and stir.Add other ingredients and stir. Cook for about 10 hrs. I started mine on high for a couple of hours then turned it to low.

Pastry:

2 cups flour
1 tsp salt
about 180g cold butter chopped
about 6 Tbspn ice cold water

Make pastry, chill then cut in half, roll out to fit base of pie dish, plus top. I used a pie funnel, put meat filling in, then topped with pastry. Brush with beaten egg. Cook 180degs C for about 35 mins.
