Pesto is one of the favourite sauces for pasta in Italy. It’s so simple: it is ingenious and delicious.
The ingredients are basil (you can find it fresh almost everywhere, but the Liguarian variety has something special), pine nuts, garlic, cheese and olive oil. The old stone mortar is much slower than the blender but also the result is different, Try it to believe it!
The trenette are a kind of pasta created especially for the pesto sauce. A good variation is to add pieces of cooked potato together with the pasta.
