About this dish
Hoshi-mochi is a winter-preserved rice cake from Tsugaru in Aomori.
Read more
A 4.5 kg batch of glutinous rice is steamed and pounded with more added water than ordinary mochi, seasoned with sugar, salt, and sesame, cut thin, braided into long strands with rice straw, dipped once in water on a bitterly cold day, frozen outdoors, and wind-dried for about two months. Repeated freezing and drying remove internal moisture and create a light porous structure, giving the alternative name kori-mochi. Long curtain-like rows under household eaves once defined February in Goshogawara, and each family had a person responsible for reading the weather and choosing the right day. The cakes may be eaten dry and crisp, lightly toasted to reveal rice sweetness, brushed with butter soy sauce, or fried. Success depends on sustained subzero cold, low humidity, clean airflow, and patient inspection.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Step
Rinse the glutinous rice repeatedly, submerge in abundant cold water, and refrigerate for 8 to 12 hours.
Spread in sieves and drain at least 30 minutes.
- 2Step
Line a large steamer with a damp cloth and spread the rice evenly.
Steam vigorously for 50 to 60 minutes, until the grains are translucent through the center and crush easily.
- 3Season
Transfer the steamed rice to a large mortar or mochi machine and pound.
Add the 1440 ml water gradually for a wetter dough than ordinary mochi, then mix in sugar and salt when almost no grains remain.
- 4Prep
Add the sesame and pound only until evenly distributed.
Spread the mochi about 1 cm thick on a water-moistened board, cool completely, and cut into 90 thin rectangles of roughly 50 g each.
- 5Step
Braid the pieces at regular intervals between clean, dry rice straw into long curtain-like strands.
Keep pieces from touching and confirm every knot is secure.
- 6Step
Choose a dry subzero day, dip the braided mochi once in clean water, and hang it under a well-ventilated outdoor eave protected from dust and animals until frozen solid.
- 7Finish
Wind-dry the mochi through roughly two winter months.
Inspect ropes and surfaces daily; if mold or persistently wet pieces appear, discard the entire affected strand rather than trimming. Finished cakes must be light, hard, and dry through the center.
- 8Finish
To serve, chew small dry pieces slowly or toast briefly on both sides over gentle heat to release the rice aroma.
Let toasted pieces cool for 1 minute because the centers become very hot.
Practical Cooking Checks
The cues that matter most while cooking.

- Avoid this
- If thawed, humid days persist or surfaces stay damp, do not continue without a controlled cool dehumidifying dryer.
- Storage and reheating
- Repeated freezing and drying remove internal moisture and create a light porous structure, giving the alternative name kori-mochi.
