Caramel Brulée: Line a baking sheet with parchment paper. In a medium pot, cook 3/4 cup sugar over medium heat, stirring occasionally with a heat-proof spatula until the sugar has melted and turns a golden caramel, about 8 minutes. Remove from the heat and carefully pour the caramel onto the prepared baking sheet. Spread in a thin, even layer and sprinkle with flaky sea salt. Let sit 5 minutes. Once hardened, crush the caramel into small pieces/shards with the back of a spoon.
