Leek and mushroom tagliatelle

Method

1. Heat a good knob of butter in a pan. Fry together the garlic and the rosemary for 30 seconds. Add the mushrooms and fry over a high heat for 5 minutes until they’re golden brown and all the moisture has evaporated. Season the mushrooms, then spoon onto a plate and set aside.
2. Add another knob of butter to the pan and fry the leeks over a low heat for 10 minutes until softened. Add the wine and bubble until mostly evaporated, then add the double cream. Season well, then mix in the garlicky mushrooms.
3. Meanwhile, cook the tagliatelle in boiling water for 8 minutes or according to the pack instructions, drain, then toss with the leeks and mushrooms. Season and stir in a handful of chopped fresh parsley and a good grating of parmesan or vegetarian alternative.
