175g Orecchiette pasta
75g shelled walnuts
2 cloves of garlic, peeled
2 heaped tbsp freshly grated Parmesan cheese, plus extra to serve
4 level tbsp mascarpone
Chop half the walnuts finely together with the garlic in a mini-chopper or small processor. Then combine this mixture in a bowl with the Parmesan cheese and mascarpone, and season well with salt flakes and ground pepper.
Bring a pan containing two litres of salted water to the boil and warm two pasta bowls. Add the pasta to the water, give it one good stir and let it simmer for about 12 minutes. Meanwhile, chop the rest of the walnuts (not too finely this time).
Drain the pasta in a colander, return it to the pan and quickly stir in the walnut sauce, keeping the pan over a low heat as you do so to heat the sauce through.
Serve the pasta with the extra nuts sprinkled over and some more Parmesan on the table.
