Chop the onions very fine; put them into a stewpan with some butter, and let them remain on a slow fire till they are well done, taking care not to let them burn. Pour off the butter: put in the powder and gravy; stir it about till it is well mixed; set it on a slow fire till it is all sufficiently done. Put in a little lemon-juice; when nearly done, thicken the gravy with flour. Let the rice be very well picked and afterwards cleansed; it ought to be washed in several waters, and kept in water till it is going to be boiled. Have the meat or fish ready, pat it into the stewpan, and stir it about till it is well mixed. The rice must be boiled twenty minutes quickly, and the scum taken off; the water to be thrown off and the saucepan uncovered till it is dry enough. Meat used for this curry must be previously fried.
