In a bowl, add in both warm milk and water. Add in sugar and mix. Sprinkle in the yeast and mix again. Leave it to activate for 3-5 minutes. When it gets foamy then it's ready to be used.

In a standing bowl mixer, add in the flour, melted butter, sugar, salt and the yeast mixture. Mix to incorporate and knead for 10 minutes. Form dough into a bowl and place it in a greased bowl. Coat the dough with some oil to avoid any crust forming on its surface. Cover the bowl tightly with cling film and leave the dough in a warm and draft free place until it doubles in size.

Form the dough into a log and cut it into 4 portions. Take each portion and form it into a ball. Take a ball and roll it into a disk that's a bit bigger than 8 inch (20 cm) diameter. Use a base of a pan as guidance (or any item of your choice). Repeat with the rest of the balls. Keep them between baking sheets to avoid them sticking to each other.

Take one rolled dough. Use a 8 inch base pan and press lightly to mark it on the dough. Remove the pan. Spoon in some Nutella in the marked area and spread evenly, again in the same marked area. Take another rolled dough and gently place it on top. Repeat the same and finish the stack with the final rolled dough without Nutella on top. Now carefully and swiftly slide a baking sheet underneath the stack.

Gently place the pan again on top of the stack. Carefully cut all around it and discard the excess dough. Remove the pan. Place a glass upside down on the center of the stack, press lightly. Cut the stack into 16 strips, starting from the center (the glass).

Take 2 strips, pull them a bit and twist 2 times in the opposite direction. Don't worry if things get messy, everything will turn out great at the end. Repeat with the rest of the strips.

Take the ends of 2 strips and pinch them together. Repeat the same with the rest. Remove the glass. Cover the bread loosely with a cling film and leave it for 30 minutes so that it puffs a bit.

Brush the bread with egg white. Carefully and swiftly slide a baking tray underneath. Bake it at 180°C (350°F) in preheated oven for 15 to 20 minutes or until golden brown and fully cooked. Cool on a rack. Enjoy!
