Guevina Avellana, commonly known as the Chilean hazelnut or Gevuina nut, is a nut with a rich, buttery flavor and a creamy texture. Hazelnuts have several synonyms that are used interchangeably, including filberts, cobnuts, and tree hazels. Other nut varieties, such as almonds and macadamias, have a similar taste and texture and are often used as a substitute for hazelnuts in recipes. Hazelnuts are a great source of vitamins and minerals, including vitamin E, magnesium, and potassium. They are popular in confectionery, desserts, and savory dishes, and are a favorite among pastry chefs for their versatility and nutty flavor.
