Fresh from the garden or pickled and funky on your ballpark nachos, this ubiquitous little pepper is jalapeño business. Named for Xalapa, Mexico where it was famously cultivated, it’s a worldwide star today. Although it scores a relatively low 2,000–8,000 on the Scoville scale (compared to the whopping 2,200,000 of the Carolina Reaper), it still feels plenty hot to many of us. It’s packed with antioxidants, potassium and vitamins, and its capsaicin is even a natural pain reliever. Whether you love them in salsa, by themselves or even in poppers, you can’t deny they’re a powerful little treat.
