When toasted and mixed into melted chocolate, couscous creates a surprising, satisfying candy.
In a skillet over medium-high, toast couscous in butter, stirring constantly, until golden, 2 minutes. Transfer to a paper towel-lined plate. Sprinkle with salt; let cool.
Stir couscous into melted chocolate. Lightly coat 1 1/2-to-4 1/2-inch heart-shaped cookie cutters with cooking spray.
Place cutters on a baking sheet lined with parchment. Fill with chocolate. Refrigerate until set, at least 30 minutes. Gently press chocolates out of cutters. Enjoy immediately, or store in refrigerator, covered, up to 3 days.
