Best Way to Use Hazelnuts in Home Cooking: Pie Crust, Dukka, and More | Eater

"A Portland restaurant features a signature candied hazelnut preparation called Black Hazelnuts: Oregon hazelnuts are toasted until golden, then candied with in-house black citrus powders (made by charring fresh citrus at low heat for days) in a sugar syrup, producing an intensely aromatic, nutty-fruity result. These candied nuts are served alone, used as a salad component with sweet herbs, appear on desserts such as a hazelnut semifreddo, and are incorporated into savory dishes—substituting for pine nuts in pesto or as hazelnut salsa macha for roasted pork or beef—demonstrating a wide savory-to-sweet versatility." - Elena Valeriote
