How to Choose and Peel Chestnuts

Choose chestnuts with shiny, firm shells that feel plump and heavy for their size. Avoid nuts with holes, mold, or damp, soft spots. Chestnuts that feel unusually light may be dried out or damaged by worms. As chestnuts lose moisture, the kernel shrinks and a gap can form between it and the shell. A water test can offer another clue: chestnuts that sink are generally fuller, while floaters may be dried out or worm-damaged.

How to choose fresh chestnuts

Check weight, shell firmness, and the surface together. Choose chestnuts that feel heavy and full. The shell should be shiny, firm, and taut rather than wrinkled. Avoid small holes, which can indicate worm damage, as well as mold and damp, soft spots. Do not choose chestnuts with a noticeable gap between the shell and kernel.

How to peel chestnuts easily

Before cooking, use a knife to cut an X into the rounded side of each chestnut. This gives the shell room to split as it heats. You can boil chestnuts in water for 15–20 minutes or roast them in the oven. Peel them while they are hot, since the shell and thin inner skin become harder to remove as they cool. Cover the cooked chestnuts with a towel to keep them warm while you work.

Should you boil or roast chestnuts?

Either method works. Boiling leaves the kernels softer and moister, while roasting gives them a deeper, lightly toasted flavor. The X-shaped cut helps the shell split with either method. Soaking chestnuts before roasting may help keep the kernels from drying out. Do not skip the cut: steam pressure can make uncut chestnuts crack or burst during cooking.

How to store fresh chestnuts

Store fresh chestnuts in a perforated container in the refrigerator's crisper drawer to slow moisture loss; they will keep there for a few weeks. At room temperature, they dry out faster. Cooked, peeled chestnuts should be eaten within a few days if refrigerated or frozen for longer storage. Remove any chestnuts with holes or mold before storing the rest. Because fresh chestnuts contain substantial moisture, they can mold in a sealed, airless environment; use a breathable container.

Look for plump, heavy chestnuts with shiny, firm, unblemished shells. Score each shell with an X before cooking, and peel the chestnuts while hot.
