Flavor bases are foundational mixtures used in cooking to enhance the taste of dishes. Common examples include mirepoix, which consists of diced onions, carrots, and celery, and sofrito, a blend of aromatic vegetables and herbs. These bases provide depth and complexity to various recipes, serving as a starting point for soups, stews, and sauces. Using flavor bases allows cooks to build layers of flavor in their meals. By sautéing these ingredients at the beginning of the cooking process, they release essential oils and natural sugars, creating a rich backdrop for other components. This technique is essential in many culinary traditions worldwide.
