Heat the milk until lukewarm (not warmer than 25degrees Celsius or 77 degrees Fahrenheit). Solve the yeast in the milk and leave it for 5 minutes.
Mix and knead the flour, milk, yeast, sugar and salt. Make sure you don't add the salt directly on the yeast since this will kill the yeast. Add the butter per teaspoon to ensure even distribution through the dough.
After kneading for about 10 minutes, the dough should feel soft and smooth. Then it is time to divide the dough into 9 portions. Shape the portions into balls and cover with some plastic foil. Let them rise for about 30 minutes.
