Combine beef, potatoes and carrots in a large bowl. In another bowl, sift together the flour, sugar, salt, curry powder, cinnamon and baking powder., Add to the beef mixture, along with the egg and milk. Blend thoroughly. Into a heavy skillet over medium heat, put 2 tablespoons of the oil. Dump the mixture into the pan in half-cup portions, as many as will fit at one time, flattening each other slightly with a wooden spoon. Cook, covered, for 5 minutes or until browned. Flip cakes over to brown the second side. Repeat until all the mixture is used, adding the remaining oil, a bit at a time, to prevent sticking. Makes 8 to 20 cakes.
