The spicy jalapeño is a medium-sized chili pepper that originates from Mexico. It typically measures 2 to 4 inches in length and is known for its vibrant green color, although it can also ripen to red. Jalapeños are commonly used in various cuisines, adding heat and flavor to dishes like salsas, nachos, and tacos. In terms of heat, jalapeños rank between 2,500 and 8,000 on the Scoville scale, which measures the spiciness of peppers. They are rich in vitamins, particularly vitamin C, and contain capsaicin, the compound responsible for their heat.
