Toasting hazelnuts enhances their flavor. They become smoky, and their texture becomes crisp and crunchy. After toasting, it’s important to remove the bitter brown skin for a better flavor. Spread shelled hazelnuts on a baking sheet in a single layer. Bake them at 350 degrees for 15 minutes or until the skins begin to split, stirring once. Transfer the warmed hazelnuts to a colander or dish, and rub them briskly with a towel to remove the skins.
