Preheat oven to 350°F. Line a baking sheet with parchment paper. Add pecans and toast for 10 minutes. Let cool.
Lay out the pecans, 4 pecans clustered together. Top with a dollop of caramel. Use a spoon to do that. Push the pecans in so that they stick to the caramel. Let set.
Melt some bittersweet chocolate and pour over the caramel to cover. Sprinkle with a few flakes of Maldon sea salt and refrigerate until set.
