Hot sauces are condiments made from chili peppers, vinegar, and various spices. They are used to add heat and flavor to dishes, ranging from tacos to grilled meats. The heat level of hot sauces is often measured on the Scoville scale, which quantifies the spiciness based on the concentration of capsaicin, the compound responsible for the heat. There are many varieties of hot sauces, each with unique flavors and heat levels. Popular types include Tabasco, Sriracha, and Cholula. Hot sauces can be enjoyed in small amounts or used as a cooking ingredient to enhance the taste of various cuisines around the world.
