Pesto: Liguria’s trademark sauce puts punch in pasta

Pesto is one of the most popular sauces in Italy and two weeks ago Marina and I went to the birthplace of pesto: Liguria. During our four days in the port town of Porto Venere, we had pesto on pasta, in paninos and even on pancakes. We also interviewed the instructor of a pasta-makìng school. I became so addicted I bought a bottle of his homemade pesto.
