What is one purpose of garnish in food presentation?

Garnish is primarily used to enhance the visual appeal of a dish. This is crucial in food presentation as it engages the diners visually before they even taste the food. A well-chosen garnish can add color, texture, and creativity to a plate, making it more inviting and appetizing. Effective garnishing can elevate the overall dining experience, capturing attention and stimulating appetite, as appearance plays a significant role in how food is perceived and enjoyed.

Options that focus on increasing portion size or serving as the main ingredient do not align with the intended purpose of a garnish, as garnishes are meant to complement rather than overshadow the main elements of the dish. While some garnishes might add subtle flavors, their primary role is aesthetic rather than being a prominent source of taste in the dish.
