What would pesto be without basil, or salsa sans cilantro? Whether used by the pinch or by the bunch, fresh herbs pull a recipe together by infusing the dish with unparalleled aromas and flavors.

Sometimes, when the effect you seek is subtle, refined, and delicate, a hint of herbs is enough; other times, handfuls are required.
