Real pesto is pounded, not blitzed — the difference is texture and heat. A mortar keeps the basil sweet and the oil emerald, while a food processor bruises both. In our Global Cuisines course this is the dish where students finally believe us, because they taste both versions side by side.
Farfalle's folds catch the sauce beautifully, and blistered cherry tomatoes add the acid punch that rich pesto needs.
