Methods/steps

Melt butter in a small, heavy saucepan. Add grated lemon peel, chopped herbs, cream and salt and pepper. Bring slowly to the boil and simmer for a couple of minutes, stirring all the time. Add the lemon juice to the pan and return to a boil, then take the pan off the heat and keep warm.

Cook the tagliatelle according to the package directions until al dente. Drain (not overly) and transfer to a heated bowl.

Add the sauce to the pasta, sprinkling with Parmesan cheese. Toss and serve immediately.
