When the first proof is done, put the dough on a table, press all the air out.
Divide the dough equally into 8 pieces, shape each of them into a small ball, and cover them with a cling film to rest for 10 mins.
Flatten each ball to a long oval/rectangular shape using a rolling pin. (The thinner the dough is, the easier it is to cut the strips thin.)
Roughly divide it in half, cut one half into thin strips.
Spread the garlic butter, and roll the dough from the end without the strip to the side with the strip.
Brush the muffin tin with butter.
In each muffin mold, put two roll-up doughs together like a doughnut.
Cover it and leave it in a warm place for second proof, for around 30 mins.
Preheat the oven at 175°C.
Brush some milk on top before putting the bread to bake.
Bake for 10-12 mins or until the top turns golden.
Leave it on a wire rack to cool, and keep it in an air-tight space if not consume on the same day.
