In a dry skillet on medium heat, spread pecans in a single layer and cook 3-4 minutes until toasted, stirring frequently; transfer to a bowl and set aside
½ cup toasted chopped pecans
In a medium saucepan add pecans, brown sugar, evaporated milk and butter; cook, stirring constantly until butter is melted and mixture thickens slightly (about 5 minutes);
1¼ cups light brown sugar, packed, ¾ cup evaporated milk, 1 tablespoon unsalted butter, ½ cup toasted chopped pecans
Remove saucepan from heat, add vanilla extract; taste for salt and add a pinch if you want
½ teaspoon vanilla extract, pinch of salt to taste (optional)
Allow to rest at room temperature for 3-4 minutes if serving immediately or pop it in the fridge for a few minutes; transfer to an airtight jar and refrigerate if using later
Notes
You can use whole pecans if you want or a combination of whole and chopped.Toasting the pecans takes less than 5 minutes, but you've got to keep an eye on the skillet as they burn quickly.
