Clean, wash and slowly halve the rhubarb and cut into small cubes. Mix starch with 2 tablespoons of water. Put cherry nectar and 75 g sugar in a pot. Add rhubarb and simmer for about 1 minute. Stir in starch and bring to the boil again while stirring constantly. Put the compote into a bowl and let it cool down for about 1 hour
In the meantime, soak gelatine in cold water. Mix quark, 1-2 tablespoons sugar and lemon juice. Squeeze the gelatine, dissolve and mix 2 tbsp. quark cream. Stir into the rest of the quark mixture and chill for 5-10 minutes. Whip the cream until stiff, allowing the vanillin sugar to trickle in. When the quark cream begins to gel, fold in the cream. Pour the cream quark cream into a piping bag with perforated spout. Alternately layer the rhubarb compote in glasses and chill for about 30 minutes. Crumble the meringue and sprinkle over the cream
