Mixed nuts are a snack food consisting of any mixture of mechanically or manually combined nuts. Peanuts (actually a legume), almonds, walnuts, pistachio, cashews, hazelnuts and pecans are common constituents of mixed nuts. Mixed nuts may be salted, roasted, cooked, or blanched. In addition to being eaten directly, mixed nuts can be used in cooking. Trail mix consists of nuts mixed with raisins and other dry ingredients.
