Tip: To toast hazelnuts, preheat oven to 350 degrees F. Spread nuts in a single layer in a shallow baking pan lined with parchment paper. Bake for 8 to 10 minutes or until lightly toasted, stirring a few times to toast evenly. Cool nuts slightly. Place the warm nuts on a clean kitchen towel. Rub nuts with the towel to remove the loose skins.
Cut the peel off the oranges using a sharp knife, making sure to remove all the bitter white pith.
