Raspberries selected. Put raspberries, 3 tbsp. water and 50 g sugar in a small pot, bring to the boil and simmer for about 10 minutes. Stir several times. Remove from the heat, pour into a bowl and let it cool down.
In the meantime, roughly chop the chocolate. Melt butter and chocolate in a small pot while stirring. Remove from the heat and let it cool down a little.
Beat the eggs, 75 g sugar, salt and vanillin sugar with the whisk of the hand mixer. Add the melted, cooled chocolate butter and stir well. Add flour and mix well. Spread the dough evenly into 6 preserving jars (220 ml capacity each).
Spread boiled raspberries evenly with a tablespoon. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 10 minutes.
In the meantime, beat the egg whites and lemon juice with the whisk of the hand mixer until stiff, while pouring in 75 g sugar. Continue beating until a firm, shiny mixture is obtained.
Remove the cake from the oven for a short time, turn down the oven temperature (electric cooker: 150 °C/ circulating air: 125 °C/ gas: see manufacturer). Spread the beaten egg whites with a tablespoon as a big blob on the glasses and bake for another 8-10 minutes. Then remove from the oven, place on a cake rack and allow to cool.
