Basil's way of becoming a sauce without ever touching a stove.

means A sauce made by crushing basil, garlic, pine nuts, cheese, and olive oil together, traditionally with a mortar and pestle, into a thick green paste.

from From Italian pesto, 'crushed' or 'pounded,' the past participle of pestare, 'to pound' or 'crush' — the same root that gives English 'pestle.' It traces back to Latin pistare/pinsere, meaning to pound or crush grain. The name describes the method, not the ingredients: pesto is simply whatever you get by pounding things in a mortar, which is why the classic version hails from Genoa, where basil, garlic, and pine nuts met that mortar first.
