Chicken stock refers to a broth made from simmering chicken bones, meat and vegetables in water. It is commonly used as a base for soups, stews or sauces, adding depth of flavor and body to dishes. The ingredients used to make chicken stock can vary, but typically include chicken carcasses, onions, garlic, celery, carrots, parsley, thyme, bay leaves, peppercorns, and salt. Once the cooking process is complete, the liquid is strained and clarified to produce a clear broth with a rich, savory taste. Chicken stock can be store-bought or homemade, and it's an essential ingredient in many classic dishes.
