Spaghetti alla puttanesca 2 (Naples' hookers' spaghetti)

For ➍
2 tbs extra-virgin olive oil
1 medium yellow onion, chopped
salt & black pepper
1 50 g can anchovies packed in oil
6 garlic cloves, minced
2 tbs tomato paste
½ ts crushed red pepper
750 g box or can chopped or crushed tomatoes
2 tbs drained capers
100 g pitted black olives, chopped
1 tbs chopped fresh basil
grated zest of 1 lemon
340 g spaghetti or other pasta

Bring a large pot of water to a boil. Meanwhile, put the olive oil in a medium pot over medium-high heat. When it’s hot, add the onion and season with salt and pepper. Cook, stirring occasionally, until soft, about 10 m. Add the anchovies and garlic and cook, stirring, until the anchovies disintegrate and the garlic has softened, 2 to 3 m. Add the tomato paste and continue to stir for 1 m, then add the tomatoes, capers, and olives. Cover the pot, adjust the heat so the mixture simmers gently, and cook, stirring occasionally, until it’s thick and saucy, 25 to 30 m. Stir in the basil and lemon zest, and taste and adjust the seasoning.
When the water for the pasta comes to a boil, salt it generously and add the pasta. Cook until al dente, usually 7 to 8 m, depending on the package instructions. Reserve about 25 cl of the pasta cooking liquid and then drain the pasta.

Toss the pasta with the sauce, adding the reserved cooking liquid as needed to thin out the sauce. Serve.
