Peel and core the apples but leave
whole. Place each on a double thickness of buttered greaseproof
(waxed) paper. Mix together the sugar, sultanas and nuts and pack into
the centers of the apples. Top each with a knob of butter and add 15
ml/1 tbsp wine to each parcel. Wrap tightly in the paper. Stand in a
baking tin (pan) and bake in a preheated oven at 180°C/ 350°F/gas mark
4 for 25-30 minutes until the apples are tender. Leave to stand for 10
minutes to allow the flavors to develop then serve warm, opening the
parcels at the table, and topping with chilled creme fraiche.
