Explanation

That bright green sauce on your pasta? It's probably pesto, a delicious combination of garlic, basil, Parmesan cheese, olive oil, and pine nuts. The traditional version of pesto, invented in Genoa, Italy, is salty and garlicky, and it's made by crushing all the ingredients by hand using a mortar and pestle. The word pesto itself comes from this technique — its root is the Italian pestare, "to pound or crush." If you want to be absolutely sure you're getting this original, authentic version in an Italian restaurant, you can specify pesto alla genovese, or "Genoese pesto," when you order.
