Chop the carrot, the celery & the onion & start frying in the olive oil - careful: don’t burn anything!
Add salt & pepper to taste.
Cut each salsiccia into 3-4 pieces.
Pluck the thyme leaves.
Add sugar, ground chili & cloves to the tomato pulp.
As soon as the the carrot-celery-onion mix is soft (about 10 min frying) put it aside & mix w/ the thyme leaves.
Start frying the salsicce until allover brown (about 10 min).
Combine everything in a pot: the salsicce, the carrot-celery-onion-mix, the tomato pulp & mix.
Bring to a boil, however, reduce heat as soon as the tomato pulp starts bubbling.
Put a lid on the pot & let it simmer for about 2 h.
Discard the cloves - if you find them. Otherwise give a warning to everybody at the dinner table.
