Pan-fry the shallot and garlic in 2 T olive oil on a low heat until softened.

Squeeze out the pork-mince filling from the sausage cases and fry with the mushroom until golden.

Add a glug of white wine and simmer until slightly reduced.

Pour in the tomato purée and canned tomato and stir in the rosemary. Simmer on a medium to low heat for 10 to 15 minutes, stirring occasionally.

Cook the spaghetti in a saucepan of rapidly boiling water until al dente and drain. Drizzle into the pasta the remaining 1 T of olive oil and toss to coat. Stir in the cream.

Toss the spaghetti in the sauce. Grate over a generous sprinkling of Parmesan and season to taste.

Cook’s notes: As an alternative, use beef or chicken sausages instead of pork. For a vegetarian dish, replace the sausage meat with slices of brinjal.
