Spread pecans in a single layer on a baking sheet lined with parchment paper or a silicone mat.
In a medium saucepan, combine sugar and water. Cook over medium heat, swirling the pan occasionally, until the sugar dissolves and the mixture turns a deep amber color.
Remove from heat and carefully whisk in heavy cream, butter, and salt. Be careful, as the mixture will bubble up.
Pour the caramel over the pecans, making sure they are evenly coated. Let cool completely before breaking into clusters.
Enjoy!
