- 2 free-range egg yolks
- 2 tbsp white wine
- 1 tbsp caster sugar
- 85g/3oz blackberries
- Preheat the grill to medium-hot.
- Stir together the egg yolks, wine and sugar in a heatproof bowl set over a pan of simmering water (do not allow the bottom of the bowl to touch the water).
- Whisk the mixture in the bowl using an electric whisk until thick and doubled in volume.
- Place the blackberries in an ovenproof gratin dish and pour the zabaglione mixture over the top. Grill for 4-5 minutes, or until the top of the mixture bubbles and turns golden-brown. Serve immediately.
