Lightly grease a 2 quart casserole dish. Cut in butter or margarine until mixture is crumbly. Add milk and stir just until dough forms a ball. 3 Turn dough onto a floured surface and knead until smooth. Roll out to 1 inch thick and cut out 12 4-inch circles.
Place circles on a lightly floured plate or baking sheet and set aside in refrigerator.
If using garam masala and curry paste, add them now. Add onions to pan and stir gently. Saute onions until soft, about 3 minutes. Add garlic and saute for 5 more minutes, taking care not to burn garlic. 5 Add lamb, Worcestershire sauce, brandy, port, and salt and pepper.
