Fill the biggest pan you own with water and bring to boil, with a little salt in there too.
When boiling, add pasta. Boil for a wee bit less than packet instructions say for al dente.
Whilst that's cooking, using preferably a small processor (great investment for family cooking - amazing for houmous, pesto etc) or if using a large processor you may have to make twice as much, whizz the ingredients.
Reserve half a mugful of pasta cooking water. Drain the pasta.
Add about half the pesto to the pasta. Stir in a little cream too, and a splash of pasta water. Toss really well. Taste and season. Toss once more.
Serve with a little extra virgin and a sprinkling of salt. Watch on in amazement as kids wolf it down.
