How to Make It
In a large pot of generously salted boiling water, cook the pasta until al dente. Drain the pasta, reserving 3/4 cup of the cooking water.
Meanwhile, in a food processor, combine the basil, almonds, garlic and crushed red pepper and pulse until very finely chopped. Add the pecorino and pulse until chopped. With the machine on, slowly pour in the olive oil. Season the pesto with salt and pepper.
Return the pasta to the pot and add the pesto. Using your hands, crush the tomatoes and add them to the pot. Add 1/2 cup of the reserved pasta cooking water and cook over low heat, tossing, until the sauce is thick and creamy, about 1 minute; add more of the pasta cooking water if the sauce is dry. Season the pasta with salt and pepper. Transfer to bowls and serve.
