Stock is a mineral-rich liquid crafted from simmering animal bones, vegetables and aromatic spices for a long period of time. Covered with water and a splash of vinegar, then left to simmer on the stovetop, animal bones release collagen into the stock that creates a thick and nutritious base ideal for use in soups, stews and sauces.
Brown stock is made using roasted bones that create a rich and hearty flavor, while white stock is created using raw or blanched bones for a lighter flavor profile and color.
