Beef Rendang is a flavorful Indonesian dish made with beef slowly cooked in coconut milk and a mixture of lemongrass, galangal, garlic, shallots, ginger, turmeric, and other spices. The slow cooking process allows the beef to absorb the rich, aromatic flavors of the spices and coconut milk until it becomes tender and deeply flavorful. It is often served with steamed rice and is popular in Indonesian and Malaysian cuisine.
