Peel oranges and remove all the white pith.

Bring 3 cups of sugar and 3 cups of water to a boil over medium-high heat to dissolve the sugar. Stir in St-Germain or Grand Marnier and add the peeled oranges. Remove the pot from heat, cover, and let sit overnight (up to 24 hours).

Preheat the broiler and line a rimmed baking pan with foil. Using a slotted spoon, transfer the oranges to the pan while keeping the syrup in the pot. Broil the oranges for 3-4 minutes on each side until browned in spots. If desired, this step can be skipped as the oranges are still flavorful without broiling.

Add the fresh cranberries to the syrup in the pot. Bring the mixture to a boil, reduce heat, and simmer until the berries soften and begin to pop.

Spoon the candied cranberries over the broiled mandarins. Serve immediately, chill in the refrigerator, or leave at room temperature for a few hours before serving.
