Add water chestnuts to your stir-fries, salads, or any meals where you need a crunchy consistency.
Canned, unopened water chestnuts will store indefinitely. Once opened, canned tubers will keep up to one week in a bowl of water. Be sure to change the water daily for the ‘freshest’ product.
If you find fresh water chestnuts, select those that are firm with no signs of wrinkling. These will need to be peeled prior to eating and cooking. Stored fresh tubers need to be wrapped tightly in a plastic bag for up to one week.
