Form into 2cm diameter balls with a spoon, or coat your hand with vegetable oil and roll them up by hand. Fry in about 1320F/160C oil until golden brown, and you are done .
You can eat the mealtballs as-is, or dip them in a mixture of plain mustard and soy sauce.
If you pan fry the meat mixture instead of deep frying it, you can make hamburgers. Just brown on both sides in a pan lightly coated in vegetable oil, add sake to the pan and cover with a lid to steam-cook the burgers all the way through.
