Add bread flour, plain flour, sugar, yeast, beetroot powder, and milk in a bowl.
Mix and form a dough. Knead it until it becomes a smooth dough.
Add the butter, and continue to knead until it becomes smooth dough again.
Cover and leave it in a warm place to prove for 45 mins or until double in size.
When it's ready, press out all the air, cover the dough and rest for 15 mins.
Divide the dough into 3 equal parts. Shape each of them to a ball.
Flatten each of them, and keep them round in shape.
Make 7 cuts in total, don't cut through the center though. 2 parallel cuts from the top (approx 1 cm apart), 1 at the bottom. On the left side, make 2 cuts and equally divide it into 3 parts. Do the same for the right side too.
On the left side, keep the middle triangle up, and put the other 2 triangles together, put the middle triangle on top of it. Do the same for the right side. Afterward, put the middle piece from the top to down. Repeat for all three doughs.
After the shaping, cover them at a warm place for a second proof, around 30 mins.
Preheat the oven to 180°C.
When the second proof is ready, sieve some flour on top.
Bake in the oven for 12 mins.
