1Pour the lukewarm milk, lukewarm water, instant yeast, and granulated sugar into a large bowl. Mix well and let it stand for 5 minutes.
2Add the bread flour and salt. Knead for 5 minutes.
3Add the softened butter (60 g) and knead for 10 minutes until the dough is smooth and elastic.
4Cover and let the dough rise for 1 hour in a warm place, or until it has doubled in size.
5Punch down the dough and divide it into 13 equal pieces (about 80 g each). Shape each piece into a ball.
6Take one ball and roll it flat with a rolling pin. Roll the dough tightly into a log and seal the seam well.
7Roll it back and forth briefly, then roll it flat again with a rolling pin, from a wider base towards a point.
8Cut the cold butter (195 g) into 13 blocks of about 15 g each.
9Place a block of butter at the wider end of the rolled-out dough and roll it up tightly so the butter is fully enclosed, forming a croissant-like shape.
10Place the shaped dough on a baking tray lined with baking paper.
11Brush with water and sprinkle with salt.
12Let rise for 30 minutes, or until the rolls have doubled in size.
13Bake the rolls in a preheated oven at 200°C (390°F) for 12–18 minutes, until golden brown.
14Let cool. Brush with melted butter for a glossy finish.
