hazelnuts crushed open in half
Hazelnuts are rich in monounsaturated fats and vitamin E, with good amounts of fiber, magnesium, and manganese; they also contain beneficial plant compounds and phenolic antioxidants.
About
Hazelnuts (Corylus avellana) are the nuts of the hazelnut tree, a species native to the temperate regions of the Northern Hemisphere, with Turkey and Italy being major commercial producers. The nut is enclosed in a hard, smooth shell and contains an oval, cream-colored kernel with a thin papery brown skin. Hazelnuts possess a rich, buttery, slightly sweet flavor with subtle earthy and toasted notes that intensify when roasted. When crushed open in half, the nut is split along its natural seam, exposing the kernel for easier consumption, faster roasting, and improved extraction of oils and flavors in culinary applications.
The hazelnut kernel itself is approximately 60% fat (predominantly monounsaturated), with a dense structure that becomes increasingly oily when crushed or ground. Key varieties include the Barcelona, Filbert, and Lamberta cultivars, each with slight variations in size, flavor intensity, and oil content.
Culinary Uses
Crushed hazelnut halves are used extensively in confectionery, pastry work, and chocolate manufacturing, most famously in products like Nutella and pralines. The half-shell form facilitates even roasting and toasting, which develops deeper flavor complexity. In savory applications, crushed hazelnuts are incorporated into crusts for fish and poultry, sprinkled over vegetables, or ground into sauces such as romesco and hazelnut-based pestos. They appear in both sweet and savory European cuisines, particularly French, Italian, and Turkish traditions, and are valued for textural contrast in salads, grain dishes, and baked goods.
