For the caramelised spiced pineapple, heat the sugar, the vanilla and cardamom seeds and the cinnamon in a non-stick frying pan until the sugar is melted and caramelised.
Add the pineapple and lime juice and stir. Remove from the heat and place onto a serving plate along with the pan juices.
For the sabayon, place the egg yolks, wine and sugar into a heatproof bowl set over a pan of barely simmering water and whisk continuously until the mixture is thick and frothy.
To serve, drizzle the sabayon over the pineapple.
