Mix yogurt, quark, cream cheese, sugar, vanilla sugar and lemon juice to a cream. Whip the cream until stiff (use a little cream stabilizer if necessary) and stir into the cream.
Caramelize some butter in a pan with a little sugar and add the sunflower seeds, let them brown a little, but not too long, otherwise it will be bitter. Then let it cool down a bit.
Put the red fruit jelly in a container. I always use a glass casserole dish as the different layers are nice to see. Pour the cream on the grits and spread the caramelized sunflower seeds on top.
