1 large Ruby Red grapefruit 1-1/2 tablespoons granulated sugar 1 small bunch of fresh mint, washed and dried Cut the grapefruit in half, horizontally. Then use a grapefruit knife, or sharp paring knife to cut around each segment. Sprinkle the top surface of each grapefruit half, evenly with about half of the sugar. Then use a small kitchen blow torch or the broiler to brown the sugar. If you are using the torch, simply turn it on medium-high and evenly go around until all the sugar has caramelized. If you are using the broiler, place the grapefruit halves on a baking sheet, and adjust a rack so it's directly under the flame. Broil the grapefruit just until the sugar is brown, about 3 minutes. Use a paring knife to help you insert a small mint leaf inside one side of each grapefruit segment and serve!
