Toasting nuts intensifies their flavor. Fire up a skillet (high temperature) and spread pecans, walnuts, almonds, pine nuts, etc. over its surface. Stir constantly. When the nuts start to turn brown, remove from the heat and reserve for use in salads, pasta, baked goods and more. Keep a constant eye on them during the process -- nuts can turn from brown to black in seconds.
Nuts can also be toasted in the oven (or a toaster oven). Spread on a cookie sheet, then bake at 400° F for 5 to 10 minutes. Be sure to stir the nuts occasionally while roasting. Broken pieces will toast faster than whole nuts.
