Serrano peppers are small, green or red chili peppers that pack a flavorful punch. They typically measure about 1 to 4 inches long and are known for their bright, crisp taste. These peppers are commonly used in Mexican cuisine, adding heat to salsas, sauces, and various dishes. With a heat level ranging from 2,500 to 5,000 on the Scoville scale, Serrano peppers are spicier than jalapeños but milder than habaneros. They can be enjoyed fresh, roasted, or pickled, making them a versatile ingredient in many recipes. Their vibrant flavor enhances both traditional and modern dishes alike.
