Use any nut or combination of nuts you love. Stay close to the nuts and keep them moving for best toasted results. You'll find yourself topping all kinds of dishes, from salads to pilafs to simple vegetables, with a handful of these flavor-makers. Make the nuts ahead and store them in an airtight container or bag in the refrigerator for at least a month and in the freezer for up to six months.
In a medium-sized skillet, melt the butter over medium heat. Add the nuts.
When the butter foams up, leave the nuts undisturbed for a minute or two so the nuts will toast in the foamy butter. Then stir constantly until the nuts are golden.
Transfer the nuts to a bowl and add a teaspoon of salt while they are hot, and stir to combine. Cool completely; the nuts regain their crunch when cooled.
