Separate the eggs and beat the egg whites with a little sugar until stiff. Beat the egg yolks with approx. 70 g sugar and half a vanilla pod until creamy. Add the starch and quark and stir everything well. At the end, carefully fold in the egg whites.
Pour the mixture three quarters full into buttered molds sprinkled with sugar. Bake the whole thing in a water bath at about 200 ° C for about 25 minutes. Under no circumstances should you use circulating air, because then it will not rise only on top / bottom heat.
