Toast the Hazelnuts: If using whole hazelnuts, spread them in a single layer on a baking sheet and toast in a preheated oven at 350°F (175°C) for about 10-12 minutes, or until fragrant and the skins start to crack. Let them cool slightly, then rub them in a clean kitchen towel to remove the skins. Grind the toasted hazelnuts. Alternatively, toast the ground hazelnuts in a dry skillet over medium heat for about 2 minutes, stirring constantly, until fragrant. Remove from heat and set aside. (Prep time: 5 minutes)
