About this dish
Sankaku chimaki is a plain Niigata parcel made by wrapping washed glutinous rice tightly into a triangle with bamboo leaves, tying it with rush, and boiling it in abundant water for about 2 hours.

Once cool enough to handle, the leaves and ties are removed and the rice is served with a mixture of roasted soybean flour, sugar, and salt. Written sources indicate that triangular chimaki existed in the Nara and Heian periods. Wamyo Ruijusho, a dictionary compiled between 931 and 938, records an older method using lye. The preserving qualities of bamboo leaves also made these parcels useful between periods of farm work. A local legend further connects their creation as portable battle food to the warlord Uesugi Kenshin.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Wash the glutinous rice until the water runs clear and drain it thoroughly in a sieve.
Do not soak it separately; leave it draining while preparing the leaves.
- 2Heat
Wash the bamboo leaves and rush ties thoroughly.
Heat part of the boiling water and pour it over them until pliable. Pair the leaves and, if the rush strands are long, divide them to prepare 10 sets.
- 3Step
Fold one pair of bamboo leaves into a deep triangular pocket.
Divide the rice into 10 portions, fill each pocket, and fold the leaves tightly into a complete triangle without large gaps.
- 4Heat
Tie each parcel firmly with rush so the leaves cannot open during boiling.
Check every knot and leaf end, and refold any gap through which rice could escape.
- 5Finish
Bring the remaining boiling water to a boil in a large pot and add all parcels.
Hold them below the surface with a heatproof plate and simmer gently for about 2 hours. Add hot water as needed so they remain submerged.
- 6Finish
Lift the parcels with tongs, drain, and cool until the steam subsides.
Mix the soybean flour, sugar, and salt evenly. Remove leaves and rush, cut each parcel in half, and serve one half per person with the kinako mixture.
