Wash, halve and stone the apricots and place them on a baking tray lined with baking paper with the cut surface facing upwards. Peel ginger and cut into 12 wafer-thin slices. Sprinkle the apricots with brown sugar, place the ginger slices and butter in pieces on top.
Bake in the preheated oven (electric cooker: 225 °C/circulating air: 200 °C/gas: see manufacturer) for about 15 minutes.
Meanwhile roast the almonds without fat until golden brown. Take out. Mix crème fraîche and vanilla sugar. Remove the apricots from the oven, sprinkle with almonds and serve with crème fraîche.
