Datemaki is an egg dish, a bit like sweet Tamagoyaki but cooked with fish cake. Datemaki is a part of Osechi Ryori, the traditional Japanese new year feast. There are a lot of kinds of dishes for Osechi Ryori, but Datemaki is prominent among them for its bright color and interesting shape. Datemaki is fairly sweet like some other Osechi Ryori so that it can last for at least the first 3 days of the new year
