Remove the husks of the tomatillos and wash the fruits (they have a somewhat sticky layer on them).
Chop them roughly, then put them in a large pan with the rest of the ingredients.
Bring to boil and let simmer for about 1 hour.
Remove the cinnamon stick and pour the chutney into warm sterilized jars, cover and seal.
It’s a good idea to leave the chutney for at least a month before eating, as it allows the taste to mature.
