Aromatics

Aromatics are vegetables, herbs, spices and other fragrant ingredients used to build the flavour foundation of a dish. They are often added early in cooking so their aromas can infuse fat, stock, sauces, soups and braises. The specific combination depends on the cuisine and the preparation.

Common aromatic combinations

• Mirepoix: the French combination of onion, carrot and celery, commonly used for stocks, soups and braises.
• Soffritto: an Italian aromatic base that often includes finely chopped onion, carrot and celery, cooked gently in fat.
• Holy trinity: the Cajun and Creole combination of onion, celery and green bell pepper.
• Sofrito: a term used in several Spanish, Caribbean and Latin American cuisines for different combinations of aromatics, often including onion, garlic, peppers and tomato.
• Asian aromatic bases: combinations such as garlic, ginger and scallion are used in many Chinese and other East Asian preparations.

How chefs use aromatics

Aromatics may be sweated gently in oil or butter, toasted briefly, roasted, infused in liquid or added fresh near the end of cooking. The method affects which flavour compounds are released and how prominent they become. Delicate herbs are often added later than robust vegetables or whole spices.

Aromatics versus seasoning

Aromatics build fragrance and flavour through ingredients such as onion, garlic, herbs and spices. Seasoning adjusts the final taste, commonly with salt, acid, sweetness or heat. The categories can overlap, but they describe different functions in a recipe.

Chef’s tip: Control the heat and cooking time. Sweating aromatics gently develops sweetness without deep browning, while higher heat can create roasted notes. Garlic and ground spices can burn quickly, so add them at the appropriate stage.

Key distinction: Aromatics are a broad ingredient category, not one fixed mixture; mirepoix and soffritto are specific examples.
