The old way: The beloved original, say the people of Genoa, Italy, who invented it, can only be made with their local small-leaved basil and a marble mortar. But even if you don't subscribe to such strict rules, chances are that you're using basil, garlic, cheese and olive oil.
The new way: A salty, intensely savory spin on the familiar mixture includes salt-packed capers, anchovies and parsley, plus the usual garlic, cheese and oil. Whole wheat pasta is the perfect pairing to stand up to such a complex, interesting topping.
