Pesto is an Italian sauce that originated in two separate times, the first one being the ancient Roman age and the second being the the Middle Ages in Genoa.
3/4 pound fusilli pasta 3/4 pound bow tie pasta 1/4 cup good olive oil 1 1/2 cups pesto (packaged or see recipe below) 1 (10-ounce) package frozen chopped spinach, defrosted and squeezed dry 3 tablespoons freshly squeezed lemon juice 1 1/4 cups good mayonnaise 1/2 cup freshly grated Parmesan
Cook the fusilli and bow ties separately in a large pot of boiling salted water for 10 to 12 minutes until each pasta is al dente. Drain and toss into a bowl with the olive oil. Cool to room temperature.
In the bowl of a food processor fitted with a steel blade, puree the pesto, spinach, and lemon juice. Add the mayonnaise and puree. Add the pesto mixture to the cooled pasta and then add the Parmesan, peas, pignoli, salt, and pepper. Mix well, season to taste, and serve at room temperature.
Place the pignoli, and garlic in the bowl of a food processor fitted with a steel blade. Process for 15 seconds. Add the basil leaves, salt, and pepper. With the processor running, slowly pour the olive oil into the bowl through the feed tube and process until the pesto is thoroughly pureed. Add the Parmesan and puree for a minute. Use right away or store the pesto in the refrigerator or freezer with a thin film of olive oil on top.
