Whisk egg yolks, sugar and wine and rum in a bowl with the whisk of the hand mixer over a hot water bath for 6-8 minutes until thick and creamy. Remove the bowl from the water bath and continue beating for 3-4 minutes until the cream has cooled down a little.
Wash the figs, peel if necessary, dab dry, cut off the stalk and halve the fruit. Pour wine mousse cream into an ovenproof dish (approx. 24 x 18 cm), place figs and gratinate under the preheated grill of the oven for 3-4 minutes until golden brown.
Remove the mould, allow to cool slightly and dust with icing sugar before serving.
