Hazelnut (shell-on) Calories

Spread shell-on hazelnuts in a single layer and roast them in an oven or pan over moderate heat, turning them occasionally. Remove them when they smell nutty, then let them cool before cracking; the kernels are easier to handle once cool.

Keep shell-on hazelnuts in a sealed container in a cool, dry, dark place. Their shells help protect the kernels, but warmth, light, and moisture can still affect freshness. Store cracked kernels separately in an airtight container.

Bad shell-on hazelnuts may smell stale, musty, or like old oil, and the kernels can taste bitter. Discard nuts with mold, dampness, or damaged shells; do not taste one if it looks moldy or smells suspicious.

Yes, shell-on hazelnuts can be frozen in a tightly sealed, moisture-proof container or bag. Keep the container closed while the nuts come to room temperature after freezing; opening it too soon can cause condensation on the nuts.

Yes, the kernel inside shell-on hazelnuts can be eaten raw. Crack and remove the hard outer shell first; roasting is optional and mainly changes the flavor and texture.

No, the hard outer shells of shell-on hazelnuts are not meant to be eaten. Crack them open and eat the kernel; the thin brown skin covering the kernel is edible.

First crack the shells and roast the kernels. While the kernels are still warm, rub them in a clean kitchen towel to loosen much of the thin brown skin; some skin may remain, and it is edible.

No, washing shell-on hazelnuts before storage can leave moisture on the shells and encourage mold. If they are visibly dirty, rinse them briefly and dry them completely before storing, or crack and use them soon after washing.

It is safer not to give dogs shell-on hazelnuts. The hard shells can pose a choking or digestive hazard, and the kernels are rich in fat; salted or chocolate-coated hazelnuts are especially unsuitable.
