What is it?
Ganzuki is a thick steamed wheat cake associated especially with southern Iwate and the Kesen area, and also found in Miyagi. Dark ganzuki uses brown sugar; pale white ganzuki may use white sugar and milk, with sesame and walnuts often scattered on top.
Its dense, gently chewy crumb differs from a light Western sponge. Families served it as everyday tea food and kobiri, a sustaining break during farm work.
History and local context
Iwate Prefecture records both black and white formulas, with differences in sugar, milk, soy sauce, egg and leavening. No single household formula defines the whole tradition.
A popular name story compares the round cake to the moon and the sesame to geese flying across it; it is best treated as a naming tradition rather than proven etymology.
How to enjoy it
Slice it into thick wedges and compare the molasses depth of black ganzuki with the gentler white version. Unsweetened bancha or hojicha suits both.
Brief steaming can soften a piece that has become firm. Store purchased cake as labeled and avoid leaving moist cut cake at room temperature for long.
Availability varies by maker, season, and destination.
