Japan — mochitsuki documented since Yayoi period; community ceremony since at least Nara period
Traditional mochi making uses a stone mortar (usu) and wooden mallet (kine) in a rhythmic two-person process: one person pounds steamed mochi rice (mochigome), the other folds and turns the mass between strikes. The pounding (mochitsuki) gelatinizes the glutinous rice starch, creating the characteristic sticky, elastic, glossy mass. The ceremony of mochitsuki is performed at New Year and special occasions — watching the rhythm and coordination required makes it a community event. Modern home use of mochi makers (using spinning blade) approximates the result but lacks the gelatinization quality achieved by impact pounding. Rice must be glutinous short-grain mochigome — regular rice cannot make mochi.
Neutral, slightly sweet glutinous rice taste — primary vehicle for fillings and toppings
{"Only glutinous rice (mochigome) — the waxy starch (100% amylopectin) creates stretchiness","Soak mochigome minimum 8 hours, steam until fully cooked before pounding","Pounding: high force repeated impact aligns starch molecules into elastic network","Two-person rhythm: pounder and folder must synchronize to prevent injury","Test readiness: smooth, glossy, completely unified mass with no grain visible","Work quickly: mochi becomes increasingly stiff as it cools — all shaping must happen while hot"}
{"Katakuriko (potato starch) on hands and work surface prevents sticking during shaping","Daifuku making: flatten hot mochi disk, fill with anko, gather edges, pinch closed","Kagami mochi (New Year decoration): shape two sizes, stack, decorate with daidai orange","Fresh mochi immediately after pounding: eat with soy sauce + nori or kinako + sugar","Freezing mochi: individual portions separated by parchment, freeze immediately after shaping"}
{"Using regular rice — will not become mochi regardless of pounding","Insufficient soaking — incompletely hydrated rice won't pound to smooth mochi","Letting mochi cool before shaping — cold mochi tears and cannot be formed","Over-pounding — mochi can become too sticky and difficult to handle"}
