Put the fresh yeast into a bowl, add 1 tsp sugar and the warm milk. Mix the yeast well, to completely dissolve into the milk. If you use the Thermomix, select 2 min – 37°C - Speed 2.
Let the mixture to rest for 5 minutes;
Place the rest of sugar and the rest of the ingredients needed for the dough into a large bowl and on top of them pour the mixture of fresh yeast and knead the dough using your hands or a kneading machine. I recommend you to add the flour into the bowl by using a sieve. If you use the Thermomix, KNEAD – 10 MIN;
TIP: If you want, you can add 1 tsp of vanilla extract.
Put a foil over the bowl with the dough and let it rise for 1 hour to double its volume.
After 1 hour, take out the dough and cut it into 4 pieces. Model each piece to create 4 smaller balls of dough. Roll each dough with a rolling pin on an oily surface until you have a nice dough sheet that you can then fill with the filling that you prefer. Remember, from these ingredients you will obtain two sweet breads.
For the nuts filling, chop the nuts finely using 7 sec – Speed 7. Clean the bowl and swipe it with a kitchen towel. Insert the butterfly whisk. Add the egg whites and select 4 min- Speed 3.5. You can add sugar during the process.
Pour ¼ of this mixture (or chocolate/raisins) over each dough sheet and roll it like a roulade. Then, using 2 rolled pieces, blend them to create a sweet bread.
Put the sweet bread into the backing tray and let it stay for 1 hour to increase its volume, once again.
Using 1 egg yolk and 20 gr of milk, create a mixture and cover the sweet bread, using a brush, with this mixture.
Bake the sweet bread for 45-50 minutes into the preheated oven at 180°C. You can make sure that the Sweet Bread it properly baked by inserting a tooth stick into the roll and see if it comes out clean.
Once you take it out of the oven, let them cool for at least 30 minutes before handling them. Do not cut the sweet bread until it is at room temperature.
