How to make
Put the flour in a tray, make a well in center and add the yeast, dissolved in 2 tablespoons cool water, then the sugar, eggs and salt in it. Knead the flour into a dough that is not so soft at first.
Continue kneading to obtain a smooth dough, and from time to time, add a little milk. Mash the butter and add 1/3 of the dough to it, then knead to get a homogeneous mixture.
Then add the rest of the dough to it in 2 lots. Let the kneaded dough rise at a moderate temperature for at least 4 hours before use.
