- 2 red grapefruits
- 4 large egg yolks
- 1 1/2 tablespoons good-quality honey
- 1/4 teaspoon fresh lemon juice
- 1 pinch coarse salt
- 1/2 cup heavy cream
- Remove peel and pith from grapefruits with a sharp knife. Working over a large bowl, carve out segments from between membranes, allowing them to drop into bowl. Refrigerate until ready to use.
- Whisk egg yolks, honey, 1 tablespoon water, the lemon juice, and salt in a heatproof bowl. Set bowl over a pan of simmering water; whisk vigorously until doubled in volume, about 10 minutes.
- Meanwhile, put cream into the bowl of an electric mixer fitted with the whisk attachment. Beat on medium-high speed until stiff peaks form. Remove yolk mixture from heat. Using a rubber spatula, gently fold whipped cream into yolk mixture until combined. Refrigerate zabaglione 15 minutes.
- Divide the grapefruit sections among serving dishes. Spoon zabaglione over top of grapefruit.
