- 7 each of grapefruits, navel oranges, tangerines, and clementines
- 2 tablespoons Grand Marnier (optional)
- 2 tablespoons chopped fresh mint
- 8 kumquats, thinly sliced (optional)
Cut peel and white pith from all fruit except kumquats. Slice clementines crosswise into 1/4” slices. Cut between membranes of remaining peeled fruit to release segments. Mix fruits in a large bowl. Add Grand Marnier, if using; toss gently to incorporate. DO AHEAD: Can be made 1 day ahead. Cover and chill.
Combine sugar and mint in a small food processor. Pulse until mint is finely chopped. Transfer fruit to a large bowl, scatter kumquat slices over, if using, and sprinkle salad with 2 Tbsp. mint sugar. Serve remaining mint sugar alongside.
