Food: steak and kidney casserole

One pound diced beef, two pig's kidneys, one onion, one carrot, tin of tomatoes, few mushrooms, garlic, salt, pepper plus a little water to just cover. Simmer for three hours (I like my meat to melt in the mouth).

OK, spot the hidden mistake?

This is what I cooked and I only realised when I was turning it off to let it stand over night: There's NO BUTTER or DRIPPING in the pot!!!! I'm out of dripping at the moment so, as a matter of some urgency, I threw in the remains of a part used 250g block of butter. Probably about 100g. This stew will probably do three portions, might freeze some and take it to work. There is no way to cook eggs at work, so usually I have cream and chocolate for lunch but the occasional cold serving of casserole is nice. People seem shocked to see me eat "ordinary" food.

Hee hee. I always explain that the meat is for show, the fat is what I'm eating.
