Let the sugared milk in the cans simmer in a saucepan with water for approx. 2 1/2 hours. So that it doesn`t rattle in the pot, I always put the cans on a slightly larger washcloth.
Let it cool down, open the can and mix the contents with all the other ingredients. This works best with a hand blender.
Fill into bottles, let steep for 1 to 2 days and enjoy.
I usually make double the portion because bottle open, bottle empty.
