Tossing cooked pasta with olive oil will prevent it from sticking together if you’re not going to add the sauce right away. But if the sauce is ready by the time the pasta is cooked, go ahead and toss it with the sauce instead!
Pesto gets its name from the Italian word pestare which means “to crush.” Traditionally (before food processors and electricity were invented!) it was made by crushing all of the ingredients together with a mortar and pestle. These days, it’s much more convenient to make pesto in a food processor or blender, but you could still try using a mortar and pestle if you are up for the challenge!
