The best hazelnut oil for a gourmet touch is extra virgin olive oil. It has a rich taste similar to butter but is light enough to be used in place of regular olive oils. It can also be used to replace olive oil in the pesto. Its flavor goes well with sweet and nutty flavors, making it an ideal substitute for butter when baking or grilling.
When it comes to flavor, roasted hazelnut oil is a top choice. This type of oil has a rich, nutty, and roasted flavor, which gives it a distinctive aroma.
