For the apricot curd dumplings, cover a sieve with a tea towel and drain the curd in it.
Beat eggs, mix with sugar, durum wheat semolina, flour, salt, vanilla sugar and the drained curd. Grate the zest of an untreated lemon and add. Mix to a malleable dough (if the dough is too thin, add some more flour). Cover and refrigerate for three hours.
To prepare the filling, pit apricots, soak each lump of sugar in apricot liqueur and fill into the apricot. Seal the apricot.
Fill a large ice cream scoop to the brim with the mixture. Carefully press one apricot into the center. Pour a little dough on top and press the apricot dumplings out of the scoop. Alternatively, form dumplings by hand. Cook in lightly boiling salted water for fifteen to twenty minutes. Lift out with a skimmer, drain and keep warm on preheated plates.
Serve the apricot dumplings sprinkled with poppy seeds and powdered sugar.
