Brown Sugar Broiled Grapefruit

Position oven rack about 3 inches from the heat source; preheat broiler. Line a rimmed baking sheet with foil.

Cut each grapefruit in half, then trim a thin slice off the bottom so it sits level. With a paring knife or grapefruit knife, cut around each segment; remove any seeds. Place the grapefruit halves on the prepared baking sheet. Combine brown sugar and cinnamon (or cardamom) in a small bowl. Brush each grapefruit half with butter, then sprinkle with about 2 teaspoons of the sugar mixture.

Broil the grapefruit, watching carefully and rotating the pan front to back once halfway through, until the tops are bubbling and golden brown, 7 to 12 minutes.

Meanwhile, beat cream in a small bowl until stiff. Beat in yogurt, granulated sugar and vanilla just until combined. Serve each grapefruit topped with a heaping tablespoon of the vanilla cream.
