Mix the yeast into the 100 ml lukewarm milk with 1 tsp sugar and 1 tbsp flour, and leave in a warm place for 10-15 minutes until foamy.
Add the sugar, egg yolks, the 150 ml lukewarm milk, the lukewarm melted butter and the salt to the flour, and work thoroughly into a smooth, glossy dough.
Work in the risen yeast mixture, knead thoroughly again, then cover and leave to rise in a warm place for 30-40 minutes.
Grease a bundt or similar mould with butter, and coat with the finely chopped almonds.
With floured hands, pinch off walnut-sized pieces of dough, roll each in the melted butter, then layer them in the mould, scattering a mix of sugar and chopped almonds between each layer.
Cover the mould and let rise in a warm place to double in size, about 40-50 minutes.
Bake in a 170-180°C preheated oven for 30-35 minutes, until nicely golden brown, then turn out onto a plate while still warm.
Make the wine custard: whisk the egg yolks, sugar, wine and lemon zest together over a bain-marie, beating continuously with a whisk, until it becomes a thick, foamy cream, about 8-10 minutes (do not let it boil).
Serve the baked dumplings warm, drizzled with or accompanied by the wine custard.
