Heat a large frying pan/skillet over medium-low heat. Add sugar and wait. Patiently.
3 tbsp sugar
The sugar will slowly start to melt and caramelize.
Add the nuts, and stir to combine. Stir often to keep the sugar from burning and to distribute it evenly.
1 cup pecans
Pour the candied nuts on a piece of parchment or waxed paper until cooled.
Notes
Store them in an airtight container, and they'll keep for months.If your pan has any sugar residue left on it, add some water to the skillet, and turn the heat on low. It will dissolve in minutes.You can use any type of nuts if pecans aren't your jam.
