Pesto

Herby and garlicky with rich, nutty cheese notes.

Lens analyzed

Pesto is an uncooked sauce of crushed basil, garlic, pine nuts, cheese, and olive oil, blended into a coarse, spoonable paste rather than simmered. It's tossed with pasta, spread on sandwiches, or swirled into soup.

Where it comes from

Pesto originated in Genoa, Italy, where local basil and pine nuts were traditionally crushed by hand with a mortar and pestle, which is where the sauce gets its name.

Buying it

Check the color in the jar — a dull olive-brown paste rather than bright green usually means it's oxidized or has been sitting a while.

Storing it

Refrigerate it after opening; a thin layer of olive oil over the surface helps keep it from browning as quickly.

Keeps about 1 month in the fridge.
