Hazelnuts

Hazelnuts is a pantry ingredient whose variety, moisture, natural oils and processing can substantially affect flavor, storage and cooking performance.

What Is Hazelnuts?

Hazelnuts is the edible nuts of Corylus species. It is valued for sweet, toasted, cocoa-friendly nut flavor with a thin skin that can taste slightly bitter.

How to Choose

Choose fresh crisp nuts with no rancid smell or mold. Reject products with rancid, moldy, fermented or otherwise unexpected off-odors.

Storage

Keep it airtight, cool and dark; refrigeration or freezing extends quality. High-oil nuts and seeds benefit from cooler storage because oxidation causes rancidity.

Preparation and Culinary Uses

Useful approaches include: roast and rub away loose skins, grind into praline, add to pastries, salads and sauces, or make nut butter. Consider moisture, sweetness and oil content when adapting recipes.

Best Flavor Pairings

Hazelnuts works particularly well with chocolate, coffee, pear, berries, brown butter and caramel.

Substitutions

A practical substitute is almonds or walnuts, recognizing the aroma differs. Adjust sweetness, liquid and fat as needed.

Common Mistakes

• Using rancid nuts or stale dried fruit.
• Ignoring differences in moisture and sweetness.
• Overtoasting high-oil nuts.
• Substituting sweeteners without adjusting liquid and browning.
