Cook the pasta according to package directions until tender. Reserve about a ½ cup of pasta cooking water.
Note 1: Fresh, chopped garlic adds the most pungent garlic flavor. If you use a garlic press or microplane, the garlic can burn as you cook it. So keep your eye on it as it cooks.
If you’re using jarred garlic, you might need to add more to taste.
Note 2: You can either chop the tomatoes before making the sauce or do it directly in the pan. If you choose to chop them beforehand, transfer the tomatoes to a large bowl and use a fork to break them into bite-sized pieces.
Note 3: Use more or fewer anchovies to taste. For a more delicate anchovy flavor, add them at the beginning, along with the garlic.
