Boil pasta as instructed on the box (most of them take up to 8 minutes to boil)
Meanwhile boil milk with sugar and add vanilla sugar at the end
When pasta is done, strain and add to the milk soup. Discard the water first.
Boil for 5 more minutes
When almost done, add the lemon zest
Pour into bowls with a ladle and sprinkle walnuts and cinnamon as preferred
Use skim milk if you like to cut back on calories. Any type of nuts work but I recommend walnuts for the special flavor that complements the other ingredients.
