1/2 cup white sugar
1 cup raw walnut halves (or pecans)
In a cool medium-large skillet, evenly pour sugar, coating the entire bottom of the pan. Place walnuts gently on top of sugar. Turn stove to medium-high heat. Now, leave the skillet alone, but watch carefully. In about 5-10 minutes the sugar will start to melt. As soon as most of the sugar has melted, but before it begins to burn, remove skillet from heat and quickly stir nuts to coat in melted sugar. Remove walnuts from skillet, and spread them out on a sheet of aluminum foil to cool.
