Pour the milk into the saucepan, add the butter cut into pieces. Place the saucepan over a small heat and bring the milk to the boil, but do not boil! The exact amount of milk depends on the quality of your cocoa powder and its density. Therefore, I give a minimum approximate calculation. It took a little more milk for all the powder than indicated in the recipe, but then it is better to top up more than pour out a lot of milk at once and understand that the mass is liquid.
