Habaneros are a type of chili pepper known for their intense heat and fruity flavor. They are typically small, lantern-shaped peppers that can range in color from green to orange and red as they ripen. On the Scoville scale, which measures the spiciness of peppers, habaneros can reach between 100,000 to 350,000 Scoville Heat Units (SHU), making them significantly hotter than many other common peppers. Originally from Central America and Mexico, habaneros are often used in salsas, sauces, and marinades to add heat and flavor. They are also popular in various cuisines around the world, including Caribbean dishes. Due to their spiciness, it's advisable to handle them with care, using gloves if necessary.
