In a bowl, combine the warm (body-temperature) milk, yeast and sugar together. Set aside for 5 minutes. In a separate bowl, add in the flour and salt and make a well. Pour in the yeasty milk mixture and knead until well-combined and the dough is not sticky (knead in the bowl first and then pour out onto a clean surface and knead, took me around 5 minutes).
Add the butter and knead again for another 5 minutes or until homogenous (the dough will look oily and broken but keep going and trust the process!). Place the dough into a bowl, cover and leave to proof for 1 hour or until doubled in size.
Once proofed, pour the dough out on a clean surface, roll into a log and divide into 6 (for large curry pans) or 8 (for smaller curry pans) even pieces. Keep the pieces covered while you work on each one.
