Working with Fresh Water Chestnuts

Fresh water chestnuts require some preparation before cooking. Start by washing them thoroughly under cool running water. Use a vegetable peeler to remove the brown outer skin. Slice off the top and bottom of each chestnut.

For optimal flavor, soak peeled water chestnuts in fresh water with a teaspoon of baking soda for 10 minutes. This helps remove any earthy taste. Rinse again after soaking.

Slice or chop the chestnuts as needed for your recipe. Fresh water chestnuts can be eaten raw, adding a crisp texture to salads or spring rolls.

Canned Water Chestnuts

Canned water chestnuts offer convenience but may have a slight metallic taste. To freshen them up, drain the liquid and rinse thoroughly under cold water.

For best results, soak the rinsed chestnuts in fresh water with a teaspoon of baking soda for 10 minutes. This helps eliminate any tinny flavor. Drain and rinse again before using.

Canned water chestnuts are pre-cooked, so they can be added directly to dishes or eaten as-is. Slice or chop them as needed for your recipe.

Cooking Techniques

Water chestnuts can be prepared using various cooking methods:

• Stir-frying: Add sliced water chestnuts towards the end of cooking to maintain their crunch.
• Boiling: Place in boiling water for about 5 minutes until tender.
