Kashiwa mochiOak leaf rice cakes
On 5 May, Children's Day, families in Tokyo and across eastern Japan eat kashiwa mochi: soft, flat rice cakes folded over sweet bean paste and wrapped in an oak leaf. Oak trees keep their old leaves until new ones bud, so the leaf stands for a family line carrying on. The leaf isn't eaten; it adds a faint woody scent and keeps the mochi moist. Mochi is very sticky: cut it into small pieces for young children and older people, and make sure they chew well and eat sitting down. The common mistake is steaming the dough too briefly, which leaves it pasty; steam until it turns slightly translucent, then knead. Chef's tip: dried oak leaves from Japanese grocers need a 10-minute simmer and a rinse before use; if you can't find them, wrap in cherry or bamboo leaves or baking paper.
