First thing first, soak your raisins in a good rum or Brandy for an additional touch of flavour.
Sift the flour into a bowl.
Add the dry yeast and mix (if using fresh yeast, rub it with 1 teaspoon of the total amount of sugar and then add it in the center of the sifted flour).
Warm the milk and gradually add it to the flour. Be careful! The milk should not be hot, but only slightly warm.
We add the eggs, sugar, salt, orange zest, the soft butter and we start to knead the dough.
Knead until you get an elastic dough. If the dough sticks to the hand, you can gradually add about 50-100 g of flour.
Put it in a bowl.
Cover it with food-grade plastic wrap or a clean kitchen towel and leave the dough to rise, in a warm place, away from cold air currents, for 2 hours, or until it doubles in volume.
I’ve put it to rest in the oven, turned-off of course :)
