Preparation :
Cut the head and tail off the fish. After gutting and cleaning the fish, slice the remaining parts into circles that are 7-8cm in diameter. Remove the marrow of the fish from its backbone with a long stick, Wash fish and put into a strainer. Wait for 5-6 minutes until the water drains away. Roll the drained fish in salt, lay pieces in a clean oil can. Sprinkle with enough salt to cover each layer of fish. After all the fish has been used, sprinkle again with salt, cover witha wooden lid and put a stone over the lid as a weight. Put in enough water so that it will cover up to 2 inches over the stone and drape cloth over with the corners tied tightly to fit the tin. After three days open the cloth and remove with a spoon the layer of oil which is floating over the water. Do this every three days. Repeat for 1.5-2months.
