Hazelnuts, also know as filberts, are popular in French and Italian baking. These round nuts encased in a hard shell have a delightful crunch and rich, buttery flavor that shine in quick loaf breads, especially in combination with dried fruits. Hazelnuts have a thin inner skin that can be removed, if desired. Bake the nuts on a baking sheet in a preheated 325deg.F oven, stirring occasionally, for about 10 minutes. While the nuts are still warm, wrap in a coarse-textured kitchen towel and rub vigorously to remove most of the skins.
