Why are aromatics used in marinades?

Aromatics are used in marinades to enhance the flavor profile of the dish by infusing it with rich, complex tastes and aromas. Ingredients like garlic, onions, herbs, and spices can penetrate the meat or vegetables, breaking down proteins and adding depth to the overall flavor. Additionally, they can help to tenderize the food, making it more enjoyable to eat. Overall, aromatics elevate the sensory experience of the dish, making it more appealing.
