Japanese Mochi Variations Daifuku and Kasane

Japan — mochi consumption since Yayoi period; daifuku developed Edo period; ichigo daifuku popularised 1980s; kagami-mochi New Year tradition from Heian court

Mochi (餅) — glutinous rice cake — spans from sacred ritual food to everyday snack to haute wagashi in Japan's confectionery culture. The most beloved mochi wagashi form is daifuku (大福 — 'great luck') — a soft mochi casing filled with anko (sweetened red or white bean paste), often including fresh fruit in modern versions (ichigo daifuku — strawberry daifuku is a contemporary classic). The mochi itself is made from mochigome (glutinous short-grain rice) that is steamed and then pounded in a wooden mortar (usu) with wooden mallets (kine) in the traditional kagami-biraki ceremony, or more practically made from shiratamako or mochiko glutinous rice flour mixed with water and sugar, then steamed or microwaved to a stretchy, glossy consistency. The key properties of quality mochi: extreme stretchiness (the protein network in glutinous rice creates long polymer chains), a glass-like translucent quality, and a clean sweetness from the rice. Daifuku making: stretch a small amount of warm mochi, place anko ball in centre, pull the mochi up around it and seal — requires quick hands as mochi cools and loses elasticity rapidly. Dusting with cornstarch prevents sticking during shaping.

Gentle rice sweetness in the mochi, concentrated anko sweetness inside — the textural contrast of soft elastic exterior and dense sweet filling is the defining experience
