How to make
First, dissolve the yeast with the sugar in part of the warm milk. After it bubbles, add it to the flour along with the oil, remaining milk, salt and eggs but set aside 1 yolk for smearing the loaf on top.
Knead a medium soft dough and leave it to double in volume, covered with foil. Divide it into 3 balls. Roll out each one into a round sheet and smear it with butter. Arrange the sheets one atop the other, without smearing the last one.
Cut it into 16 triangles. Pair up the triangles, putting one atop the other and cover. Leave the loaf to sit for 20 min.
Smear it with the egg yolk beaten with 1 tbsp oil, sprinkle with the seeds. Bake in a moderate 340°F (170 °C) oven until ready. Take it out and smear with a little butter for a soft crust, then break it into pieces and serve.
