if you were to wander into one of the estimated 46,000 convenience stores in japan, you would eventually come upon a section of the refrigerated shelving designated for rice balls. some of them contain extravagent ingredients, like spiced cod roe, chopped green onions, and fresh wasabi. others are decidedly non-japanese in flavor, such as the surreptitiously bright yellow dry curry rice balls.
but no matter where you go, regardless of whether you are in a 7-11, familymart, circle k, daily yamazaki, or lawson, you will undoubtedly find a rice ball labeled “sea chicken.”
it contains, as you might guess, a 1:1 mixture of tuna and mayonnaise. they are the cheapest for a reason. namely, because they are just awful.
