The larger myeolchi are used in the stock of many Korean dishes like soondubu.
Personally I like to eat the larger dried anchovies by themselves (after removing the heads and intestines, or course : )). I dip them in hot pepper paste and eat them with rice. Very delicious! The tiny bones of myeolchi contain a lot of calcium and are really good for you.
