A jalapeño is a medium-sized chili pepper that is commonly used in various cuisines, particularly in Mexican dishes. It typically measures 2 to 4 inches in length and is green when harvested early, turning red as it ripens. Jalapeños are known for their moderate heat, which ranges from 2,500 to 8,000 Scoville Heat Units, making them a popular choice for adding flavor and spice to salsas, sauces, and other recipes. These peppers are rich in vitamins A and C, as well as antioxidants, which can provide health benefits. They can be eaten raw, pickled, or cooked, and are often used to stuff dishes like jalapeño poppers. Their versatility and distinctive flavor make them a favorite ingredient in many households.
