When hungry visitors suddenly appear at the door, all you can do is make a quick plate of pasta. This creamy mascarpone tuna sauce is perfect for these situations, because it can be made in a jiffy and the sauce does not require any cooking. All you have to do is wait for the pasta to cook and lay the table!
Boil the pasta until it is 'al dente'. Meanwhile, chop the parsley and anchovy together. Add the tuna and mascarpone with a couple of tablespoons of the pasta cooking water. Blitz to a creamy consistency with the help of a hand-held blender. Drain the pasta, stir in the sauce and serve hot. If necessary, add another tablespoon of the pasta cooking water: the texture should be creamy but not too thick.
