5,000-15,000 SHU. The Serrano pepper is a small, slender chili known for its bright, crisp flavor and moderate to high heat. Native to the mountainous regions of Mexico, it typically measures 2–4 inches long and matures from green to vibrant red. It’s hotter than a jalapeño but still approachable for most spice lovers. Serranos are commonly used fresh in salsas, sauces, and pickled preparations, retaining their heat even when cooked. Their thin skin makes them ideal for blending without peeling. Popular in Mexican and Southwestern cuisine, serranos offer bold flavor and fiery versatility.

*Mature peppers can range from green to orange to red.
