- 6 cups citrus supremes (any combination of grapefruit, orange or tangerine segments with peel, pith and membranes cut away)
- 1 cup granulated sugar
- 12 egg yolks
- 1 cup Frangelico
In a metal bowl on top of a pot of simmering water, whisk sugar, egg yolks, and Frangelico until pale yellow and thickened. Arrange fruit in one layer in a baking dish. Spoon zabaglione over top of fruit, smoothing well. Dust with powdered sugar and place under the broiler until golden brown. Sprinkle with hazelnuts and serve immediately.
