Which of the following best describes the role of herbs in a dish?

Herbs primarily serve to provide balance and flavor enhancement in dishes. They add complexity, depth, and freshness, allowing the overall flavor profile to be more vibrant and nuanced. The distinct aromas and tastes of herbs can transform a dish, complementing and contrasting other ingredients, which is essential in culinary practices.

While herbs may occasionally have other functions depending on the dish, such as contributing to a base or adding a hint of sweetness, their primary purpose is flavor enhancement. They are not typically used as thickening agents or base ingredients like certain vegetables or starches, nor are they primarily utilized to increase sweetness, which is more associated with spices or sweeteners.
