Skipping aromatics in a curry will result in a less complex and flavorful dish, lacking depth and nuance. The curry will likely taste flat and one-dimensional.
Aromatics, such as onions, garlic, ginger, and chilies, form the foundation of most curries. They are typically sautéed in oil or ghee at the beginning of the cooking process. This process releases their essential oils and flavors, which infuse the entire dish. Each aromatic contributes a unique element: onions provide sweetness and body, garlic adds pungency, ginger offers warmth and spice, and chilies contribute heat. When these aromatics are omitted, the curry lacks these crucial flavor components. The spices, while still present, will not have the same depth or complexity, resulting in a blander and less satisfying final product. The layering of flavors, which is characteristic of a well-made curry, will be absent. Think of it like building a house without a foundation – the structure might stand, but it won't be as strong or resilient.
To maximize the flavor of your aromatics, sauté them slowly over medium-low heat until they are softened and fragrant, but not browned or burnt. Burnt aromatics can impart a bitter taste to the curry.
