Whisk the egg whites with a pinch of salt until stiff peaks form. Fold in 40g of the sugar whisking in gently. Pour the Kinnie in a sauce, scrape in halve of the vanilla pod and half of the zest of the orange. Place over moderate fire and bring to a simmering point. Take spoonfuls of the meringue and poach gently in the Kinnie syrup. Carefully lift the poached meringues with a slotted spoon and put on a plate. Allow the Kinnie to reduce into a thick caramel consistency, pour in the cream to obtain a light caramel sauce. To make the custard, heat milk with the remaining vanilla and orange zest until just before boiling point. Whisk the egg yolks with the remaining sugar, then pour over the hot milk. Return to a clean pot and cook gently, stirring continuously until sauce thickens slightly, be very careful at this stage especially not allowing the milk to boil. Pour the custard into a cold jug to stop it from cooking, remove the vanilla pod and zests and stir in the liqueur. Divide the slightly cooled sauce into serving bowls and the islands on top. Garnish with berries and drizzle with the caramel.
