Dry pasta holds heat better than fresh
Add darker-colored briny olives and capers last for the final toss so the summer tomatoes keep their bright color.
Look for dried pasta labeled "durum semolina" or "durum wheat." I like to use this type of hard-wheat pasta because it's good and chewy and holds heat longer than fresh pasta. De Cecco, Barilla, del Verde, and Ronzoni are all good—you don't need to buy expensive gourmet pasta. And durum semolina pasta is typical of southern Italy, where these raw sauce recipes find their roots.
Use pasta shapes that hold the ingredients. Raw sauces aren't smooth like cooked sauces, so the pastas that match them best are those with hollow areas to trap the ingredients, such as shells, cavatelli, orecchiette, penne, or rigatoni. Use flat pastas like fettuccine to soak up juicier sauces.
To cook one pound of pasta, use five quarts of abundantly salted, vigorously boiling water. Never put oil in the water; oil and water separate, and this does nothing for the pasta.
Tasting the pasta is the only way to tell if it's done. It should be cooked al dente, "to the tooth." It shouldn't melt in your mouth (that's too soft), nor should you have to bite down (too hard). You should feel the texture of the pasta with a little nip of the teeth, with no chalky center.
