Red chili peppers, often simply referred to as "red chili," are spicy, flavorful fruits that belong to the Solanaceae family, specifically the Capsicum genus. They are widely used in cooking to add heat and flavor to dishes. Red chilies are typically harvested when fully ripe, which gives them their vibrant red color.
The level of heat in red chili peppers is measured using the Scoville Heat Scale, which assesses the amount of capsaicin (the compound responsible for the spiciness) present in the peppers. Red chilies can vary in heat from mild to extremely hot, with varieties like jalapeños on the lower end of the scale and the Carolina Reaper or Ghost Pepper on the hotter end.
