Buying fresh chestnuts
Once you find them, select chestnuts that are heavy for their size with tight, shiny skin. Avoid nuts that have mold on their surface or rattle in their shell�this means they�re old.
Store the chestnuts dry, cool and dark. They should be eaten within a few weeks.
Should you already have peeled them, store them in the fridge in an airtight container and enjoy them as soon as possible or within a few days (or put them in an airtight container in the freezer).
