Spicy Chinese cuisine is a popular style of cooking originating from the Szechuan and Hunan provinces in China. Szechuan cuisine is known for its bold flavors, including garlic, chili peppers, and Sichuan peppercorns. Hunan cuisine is also known for its spiciness, but it is more focused on the flavor of the ingredients rather than the heat. Both styles of cooking are popular around the world and have become staples of Chinese restaurants.
