Line a baking tray (inside dimensions 24 x 36 cm) with baking paper and spread a thin layer of oil on it. Beat the egg white with the whisk of the hand mixer until stiff. Add 100 g sugar and continue beating for a few minutes. Mix 75 g sugar, 1 packet vanilla sugar and starch. Add the vinegar to the egg white mixture and continue beating until the mixture is very firm and shiny
Pour the egg whites onto the baking paper and spread evenly. Bake in the preheated oven (electric cooker: 150 °C/ convection oven: 125 °C/ gas: see manufacturer) for 25-30 minutes until the surface is crispy and the base separates easily from the baking paper. Remove and leave to cool on the baking tray for a few minutes. Place 1 piece of baking paper on a rectangular cake rack and dust with icing sugar. Turn the meringue plate over onto the baking parchment, remove the baked paper. Cover the plate with a slightly damp tea towel and let it cool down
Raspberries selected. Drain the apricots well and mash them. Stir the quark, mascarpone, 25 g sugar and 1 sachet of vanillin sugar until smooth. Pour the cream onto the meringue platter and spread it out, leaving about 1 cm of edge free all around. Spread apricot puree in streaks on the cream, then spread the raspberries on top. Roll up carefully from the long side and chill for about 1 hour. Dust with icing sugar and serve immediately
