The key ingredients of a basic stock are bones (or meat), mirepoix (onion, carrot, celery), aromatics (like herbs and spices), and water. Bones provide collagen for body, meat adds richness, and mirepoix contributes a foundational flavor base.
A well-made stock is the foundation of many delicious dishes. Let's break down the role of each key ingredient:
Bones (or Meat): Bones are crucial for a rich, flavorful stock. They contain collagen, which breaks down into gelatin during simmering, giving the stock body and a silky mouthfeel. Roasting the bones before simmering enhances their flavor. Meat, while not always used, adds a deeper, richer flavor to the stock. Chicken carcasses, beef shanks, or fish bones are common choices.
Mirepoix: This is a classic flavor base consisting of onions, carrots, and celery. The ratio is typically 2 parts onion, 1 part carrot, and 1 part celery. Mirepoix provides a subtle sweetness and savory depth to the stock. The vegetables are usually roughly chopped, as they will be simmered for a long time.
Aromatics: These are herbs, spices, and other flavorings that add complexity to the stock. Common aromatics include bay leaves, peppercorns, parsley stems, and thyme. They should be added towards the end of the simmering process to prevent their flavors from becoming bitter.
Water: Water is the liquid base of the stock. It extracts the flavors from the bones, meat, mirepoix, and aromatics. The amount of water used will affect the concentration of the stock.
The simmering process is essential for extracting the maximum flavor from these ingredients. A long, slow simmer allows the flavors to meld together and develop a rich, complex character.
Avoid adding salt to your stock while it's simmering. It's better to season the final dish, as the stock will reduce and the salt concentration will increase, potentially leading to an overly salty result.
