Trofie al pesto is a classic dish from Liguria, and basil pesto is a perfect fit for this shape, as the rustic texture of the pasta seems made to catch more of the sauce.
Add in the cup of a blender the basil, the garlic, 6 tablespoons of parmesan, 2 tablespoons of pecorino cheese, the pine nuts and 1 tablespoon of EVOO. Blend until the ingredients come together in a paste.
Continue blending as you gradually add the olive oil, until everything is blended together and it appears creamy.
TO MAKE THE TROFIE
Put 2 cups of semolina in a bowl on the table, add a pinch of salt and enough water to make a homogeneous and elastic dough. Add the water little by little.
Knead the dough for ten minutes and then let it rest outside the refrigerator for about 30 minutes, covered with a cloth.
Then, using your thumb and forefinger, take a piece of dough and roll it with the palm of your hand on the dough board into twisted dumplings, with the ends thinner than the middle part.
Place a pot of water on the stovetop and bring to a boil. When the water boils, add 2 tablespoons of salt (see notes), the green beans and the potatoes, boil for 10 minutes, remove with a spatula and cool in cold water with ice to keep their light color.
Then add the trofie to the pot of boiling salted water and cook for 4 minutes. Meanwhile, put the pesto sauce in a bowl, reserving 2 tablespoons of the cooking water and add it to the bowl with the pesto. This will dilute the pesto and coat the trofie better. Add the green beans and potatoes.
Drain the trofie and add it to the bowl with the pesto, potatoes and green beans. Mix well and top with some toasted pine nuts and fresh basil leaves.
