Goan Chicken Vindaloo is a popular variation of the traditional Vindaloo recipe. It is a spicy and tangy curry that combines the flavors of Indian and Portuguese cuisines. The dish is made by marinating chicken in a mixture of vinegar, garlic, ginger, and a blend of spices such as red chili powder, cumin, and cinnamon. The marinated chicken is then cooked with onions, tomatoes, and a paste made from ground spices and vinegar. The result is a rich and flavorful curry that is best enjoyed with steamed rice or bread.
