Mix all the dry ingredients in a bowl, except the butter.
Add in the cold milk and mix, until everything is incorporated. Allow this dough to rest for 5 minutes.
Knead the dough on slow speed, for 3 minutes, moving to high speed, until the dough is almost developed.
Gradually start adding in butter. Check your butter, it should be pliable and show a finger indent when lightly pressed. If it’s still cold, place in the microwave for 10 seconds or so. It shouldn’t be melted, just pliable.
Add the butter to the bowl, one small chunk at a time. Wait until each chunk is absorbed into the dough before adding the next.
Allow your dough to double, at room temperature, this should take about 30 minutes at 29-30 degree Celsius.
Knock the air out of the dough and, divide it into three equal parts.
Roll it and braid the dough as shown in the video.
Place the dough in a greased pullman loaf tin and allow it to proof.
