Beef and Kidney Stew

I bought diced kidney and cubed beef separately with the intention of making a steak and kidney pie. What was left over became a  beef and kidney stew.

The beef was cooked according to the usual procedure, being first browned in some sunflower oil, along with the diced kidney. Then sliced onion was added, plus boiling water. Simmer under glass for an hour, adding the sliced mushroom half way through, and the beef and vegetable stock. Add a desert spoonful of dark soy sauce. Stir occasionally.

Serve with boiled potato, and boiled or steamed sugar snap peas.
