Melt the butter or olive oil in a large saucepan and add the garlic and rosemary and allow to infuse.
Add the chopped tomatoes and season with salt and pepper and to taste with the sugar. Cook the tomatoes until they have begun to soften, or for about 5 minutes.
Add the sausage to the pan with the chilli flakes, cream, chopped parsley, worcestershire sauce and tomato ketchup.
Simmer with the lid off until the mixture has reduced by half, 10-20 minutes, stirring frequently. Take off the heat and check and adjust the seasoning.
Meanwhile, cook the pasta in a large pan of salted boiling water until it is slightly al dente (according to pack instructions). Once cooked, drain and toss with the sauce.
Scatter each serving with the grated parmesan cheese and serve immediately.

I omitted the ketchup, (personal preference.) It was very good, will make again.
