Put flour, sugar and salt in a bowl. Make a depression in the middle. Crumble yeast into it. Pour a little milk over it, cover with a little flour and leave to rise in a warm place for about 15 minutes.
Add fat and remaining milk and knead with the dough hooks of the hand mixer to a smooth dough. Cover the dough again and let it rise for about 30 minutes. Knead in the raisins. Divide the dough into three thirds and form into strands of about 60 cm each.
Braid the strands into a plait and lay them on a greased baking tray to form a wreath. Let it go again for about 15 minutes. Whisk the egg yolk and cream, brush the plait with it and bake in a preheated oven (electric range: 200 °C/ gas: level 3) for 35-40 minutes.
