A gourmet is a person who is knowledgeable in fine food and drink.
Spread them in a single layer in an ungreased pan. Bake at 350ºF, stirring and checking until they are done. They are toasted when lightly browned. Bake almonds, pecans and walnuts for 7 to 12 minutes. Bake pine nuts for 5 to 7 minutes.
Place 1/2 cup at a time in the bowl of a food processor or blender. Process them in short pulses just until ground. If you grind them longer, you will end up with nut butter (which works well with peanuts).
To Roast Hazelnuts
Preheat oven to 375 degrees F (190 degrees C). Remove the shells of the nuts if this has not already been done, and arrange the shelled nuts in a single layer on a baking sheet. Roast until the nuts begin to turn a golden brown, about 5 to 10 minutes.
