Peeling hazelnuts may seem like a minor task, but removing at least part of the thin brown skin covering the nut allows for a more delicate flavor, a more pleasant texture, and better results in many preparations. Roasting is the simplest and most practical method: the heat dries out the skin, making it brittle and making it easier to separate from the hazelnut's surface.

This technique is especially useful when using hazelnuts to make creams, pralines, dough, biscuits, cakes, or decorations. Roasting also intensifies the natural aroma of the nuts and makes the flavor fuller and more aromatic.

However, the skin doesn't always come off completely. Some hazelnuts may retain small residues even after being rubbed. This isn't a problem: the remaining skin is edible and won't compromise the success of the recipe. The goal is to remove most of the skin without damaging or burning the hazelnuts.

How to toast hazelnuts in the oven

To begin, spread the shelled hazelnuts on a baking sheet, forming a single layer. It's important not to overlap them, so the heat reaches them evenly.

The oven must be preheated to approximately 160-170 ° C In static mode. A moderate temperature allows you to toast the hazelnuts gradually, reducing the risk of burning the surface before the skin dries.

The time required generally varies between 8 and 15 minutesDepending on the size of the hazelnuts, the quantity on the pan, and the oven's specifications, it's a good idea to stir them or gently tilt the pan once or twice during toasting to expose each side to the heat.

Hazelnuts are ready when they begin to release a strong aroma and the skin appears darker, drier, and slightly raised. Don't wait until they're completely browned: the nuts continue to cook for a few moments after being removed from the oven and can burn quickly.

How to remove the cuticle

Once removed from the oven, the hazelnuts should rest for a minute or two, just long enough to handle them without burning yourself. They should still be warm, however, because the skin peels off more easily before they cool completely.

The hazelnuts can be placed in the center of a clean, dry cloth. It's best to use a lint-free cloth that's not too delicate, as it could stain slightly.

Wrap the cloth around the hazelnuts and rub them vigorously but gently. The friction breaks the dry skin and separates it from the surface. After a few seconds, unfold the cloth and check the result.

Cleaned hazelnuts can be placed in a bowl, while those that are still heavily coated can be rubbed again. It's normal for some fragments to remain attached, especially in the recesses of the nut.

Once finished, the skins can be removed by gently shaking the cloth or passing the hazelnuts through a large-mesh strainer. Washing them isn't necessary, as the water would remove some of the crunchiness created by toasting.

Can you toast them in a pan?

When using a small amount of hazelnuts, you can use a pan instead of the oven. Choose a thick-bottomed container and heat it over low heat, without adding oil or other fats.

The hazelnuts must be stirred constantly to prevent them from toasting only on one side. Within a few minutes, their aroma will become more pronounced and the skins will begin to dry out.

This method is quick, but requires more care. Direct contact with the hot surface can cause burnt spots, especially if the flame is too high or the hazelnuts are not moved frequently. For more even roasting, the oven is generally the best option.

Why do some hazelnuts peel better than others?

The ease with which the skin peels depends on several factors. Some varieties have a tighter skin, while others peel almost completely after a few minutes of roasting.

Freshness also affects the result. Well-stored, dry hazelnuts with no surface moisture toast more evenly. If they've been stored in a humid environment, the skin may remain more elastic and difficult to remove.

Too little roasting prevents the skin from drying, while overcooking risks making the hazelnuts bitter. It's therefore important to observe the color, smell the aroma, and adjust the roasting time to your oven.

How to avoid burning them

Hazelnuts contain natural oils that react quickly to heat. This means they can go from lightly toasted to burnt in a short time.

It's best not to leave the oven during the last few minutes of cooking. If the aroma becomes too intense or the color darkens rapidly, remove the pan immediately.

Once out of the oven, it's helpful to transfer the hazelnuts from the hot metal to a cloth or plate. Leaving them on the hot baking sheet could prolong the cooking process and make some parts too dark.

How to use peeled hazelnuts

Roasted, peeled hazelnuts can be chopped and added to cake, cookie, and tart batters. When chopped, they're perfect for decorating desserts, ice cream, custards, and frozen desserts.

They can be blended for a longer time to make a hazelnut paste, useful as a base for spreads and fillings. In this case, it's important to let them cool completely before processing, as the heat generated by the blender could make the mixture too runny.

In savory dishes, they can enhance salads, pestos, stuffings, cooked vegetables, and cheese-based dishes. Their toasted flavor also pairs well with squash, mushrooms, radicchio, and white meats.

How to store them after roasting

Before storing hazelnuts, they must be completely cooled. If they are sealed while still hot, steam can build up inside the container and compromise their crunchiness.

It's best to store them in an airtight container, away from light, heat, and humidity. Since they contain natural fats, they can develop a rancid flavor if left too long near the stove or exposed to air.

To best maintain the aroma and consistency, it is advisable to toast only the necessary quantity or consume them within a reasonable time.

In conclusion

To easily peel hazelnuts, simply toast them in the oven at a moderate temperature, check them carefully, and rub them while still warm on a clean cloth. The heat dries out the skin and makes it easier to remove.

It's not necessary to remove every single fragment: small residues are normal and completely edible. Properly roasted hazelnuts enhance their aroma, improve their texture, and make them ready for use in numerous sweet and savory recipes.
