Chestnut

A quintessential autumn delicacy (botanically a nut). Ibaraki Prefecture ranks first nationally, followed by Kumamoto and Ehime. An indispensable part of Japan's autumn food culture, appearing in chestnut rice, Mont Blanc cakes, and kuri-kinton. Cold storage after harvest enhances sweetness, leading to growing popularity of aged chestnuts

Taste & Texture

How to Choose

  • Choose chestnuts with glossy outer shells that feel heavy for their size.

  • Avoid shells with insect damage or dark spots.

  • They should feel firm when squeezed.

  • Discard any that float in water, as they may be hollow.

How to Store

  • Raw chestnuts are sensitive to drying; store in a plastic bag in the refrigerator.

  • Kept at low temperature (0-3°C) for 3-4 weeks, starches convert to sugars and sweetness increases.

  • For long-term storage, blanch then freeze.

Shelf life 1 month refrigerated (sweetness develops over time), 3-6 months frozen
