Serranos are a type of chili pepper known for their medium heat and bright flavor. They typically measure about 2 to 4 inches long and are green when harvested, turning red as they ripen. Commonly used in Mexican cuisine, serranos add a spicy kick to dishes like salsas, sauces, and tacos. These peppers are often confused with other varieties, such as jalapeños or habaneros, but they have a distinct taste and heat level. Serranos are rich in vitamins A and C, making them a nutritious addition to meals. They can be used fresh, roasted, or pickled for added flavor.
