Cook the pasta in a pot of well-salted boiling water until it’s just al dente, no more. The pasta may still get a little softer when mixed with the sauce before serving.
8 ounces spaghetti
Drain the pasta and reserve about ½ cup of the pasta water.
¼ cup reserved pasta water
While the pasta is cooking, heat olive oil over medium heat.
2 Tablespoons olive oil
Add the tomatoes (and anchovies, if using) and cook for about 5 minutes, stirring occasionally and crushing the tomatoes with a wooden spoon.
8 ounces cherry tomatoes, halved, 1-2 anchovies (optional)
Then add the garlic, salt, and pepper, and cook for another minute (be careful not to burn the garlic).
2 cloves garlic, thinly sliced (about 1 Tablespoon), ½ teaspoon kosher salt (plus more for cooking pasta), ½ teaspoon freshly ground black pepper
Add the reserved clam juice from the can and ¼ cup of the pasta water.
½ cup clam juice, reserved from can, ¼ cup reserved pasta water
Increase the heat if needed and stir frequently to emulsify the pasta water with the clam juice, for about 3 minutes.
Reduce heat or remove from heat and add red pepper flakes (if using), cooked pasta, clams, and parsley. Mix very well to make sure the pasta is evenly coated.
8 ounces spaghetti, 6 ounce can of chopped clams, ¼ teaspoon red pepper flakes (optional), ½ cup roughly chopped Italian flat-leaf parsley
Add 2 tablespoons of pure clam juice and 1 tablespoon of freshly squeezed lemon juice.
2 Tablespoons pure clam juice (bottled), 1 Tablespoon freshly squeezed lemon juice (about ½ lemon)
Mix one more time and serve with a slice of crusty bread and a glass of your favorite light red or white wine.
