The Serrano is a bright, medium-hot Mexican chili that is smaller and noticeably hotter than a jalapeño. It delivers a crisp, grassy heat and is a staple in fresh salsas, pico de gallo, and guacamole across Mexico and the American Southwest.
Serrano peppers are small (1–4 inches long), slender, and cylindrical with smooth, glossy dark-green skin that ripens to bright red. They have thinner walls than a jalapeño but very juicy flesh. Heat is consistently medium-hot (10,000–23,000 SHU).
