주먹 (ju-mok) means “fist” in korean. It is rice ball that’s as big as a fist. It is made with both hands, you get a scoop of freshly cooked rice, fold-in tuna and kimchi, then form a ball, then roll it on dried seaweed (김 / kim) and spicy sesame seeds. It just costs about 1000 to 1500 Korean won. Very cheap for a ready-to-go meal.
Now I’m craving!
