Sag Paneer

Cheese:
Bring 4 cups low fat milk to a boil. Remove from heat. Stir in 1 1/2 cups buttermilk. Stir until curds form and whey is clear. Strain through cheesecloth. Put a weight on top after it is drained to pack it down.

Spinach:
2 packages frozen spinach, chopped and thawed
1/4 cup margarine
1 onion, finely minced
1 heaping teaspoon coriander
1/2 teaspoon cumin
1 teaspoon turmeric
3/4 teaspoon salt
Coarsely ground pepper
1 cup yogurt

Cook onions in margarine. Add spices; cook, the add spinach. Cook 5 to 10 minutes. Add yogurt, but don't boil — just heat, then add cheese, cut into cubes.
