Hazelnut, found in the nut of the hazel tree, is prized for its rich, sweet, and slightly earthy flavor. Physically, hazelnuts are small, round, and have a hard, smooth shell that encases a creamy, off-white kernel. When it comes to scent, hazelnut carries a warm, buttery aroma that is distinctly nutty. After being roasted, the aroma deepens and intensifies, bringing out a toasted, somewhat woody fragrance with hints of caramel. This combination of taste and fragrance makes hazelnuts a popular choice in culinary applications, particularly in desserts and coffee flavorings, and contributes a comforting, inviting scent profile in various aromatic blends and perfumes.
