Tomatoes may get more attention, but throughout Italy lemon is also often found in pasta.
Along the Amalfi Coast, ring-shaped calamarata pasta comes with clams, parsley, garlic and fried strips of a sweet local lemon. In Sicily, shortcrust pastry is sprinkled with roasted pistachios, parmesan, and lemon juice and zest. And in Rome, the juice is whipped with olive oil, cream and Parmesan cheese for al dente tagliatelle.
The sour, subtly sweet citrus balances the starch of the noodle and the weight of the sauce, working much like the dose of freshly ground black pepper that offsets the pecorino romano in the cacio e pepe. And it performs much the same role as the tomato, providing acidity that runs through the cheese.
In fact, the combination of lemons and pasta is arguably more traditional than the red sauce itself, as the fruit arrived in Italy at least 1,500 years before tomatoes.
Lemon features prominently in a batter in our “COOKish” book, which limits recipes to just six ingredients without sacrificing flavor. Crisp, invigorating lemon zest and juice enhance the flavor of garlic, pancetta and capers, while a dusting of crispy golden breadcrumbs adds texture.
This spaghetti is also a one-pot wonder: we cook the pasta in a minimal amount of water, and the resulting starchy liquid forms a slightly thickened sauce that coats the noodles.
