Drain the apricots. Heat 100 ml milk. Crumble yeast, dissolve in it. Knead 250 g flour, salt, 1 tbsp. sugar, lemon zest, 1 tsp. butter and yeast milk to a smooth dough. Cover and leave to rise in a warm place for about 30 minutes
Knead the dough again well and divide it into 4 equally sized pieces. Place one apricot half on each. Cover the dough with lightly floured hands and form into balls. Cover and leave to rise for a further 20 minutes
Heat 1/4 l milk, 1 tablespoon sugar and 1 teaspoon butter in a large pot or roaster (with a tightly closing lid). Place the dough balls next to each other, cover and cook over a low heat for about 30 minutes. Do not open the pot in between, so that the dumplings do not collapse
Heat 1 tablespoon of butter. Fry 1 tablespoon of sugar and poppy seeds. Arrange the yeast dumplings with the poppy seed butter and the remaining apricots
