Ground Beef Curry (trust me)

I know it sounds weird, considering that Indians don't eat cows and all, but this was delightful and quite easy. I made this based on several recipes I found online at recipezaar.com. I didn't have everything any one of the recipes called for, so I made up my own. As always, measurements are not exact.

1/2 lb ground beef
1/2 onion-chopped
2 cloves garlic-minced
1 Tbsp butter
1 Tbsp flour
1 cup beef stock
1/2 cup carrot-chopped
1/2 can (the little ones) tomato paste
1/4 cup water
1 tsp tumeric
2 tsp curry powder
1/2 tsp cinnamon
dash of cayenne pepper (depends on how spicy you like it)
1 Tbsp brown sugar
splash vinegar
3 handfulls frozen peas
1/2 cup plain yogurt

Brown beef with onions. Add garlic & butter. Add flour and stir. Add stock and wait for for the sauce to thicken. Add the rest of the ingredients except the peas and yogurt. Simmer for 30 minutes or until carrots are cooked through. Add more water if it starts to look too thick. Add yogurt and peas and simmer until heated through.

Garnish with a dollop of yogurt and serve with basmatti rice.
