About

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.

Backstory

Named after the mountains of Puebla and Veracruz in Mexico, the Serrano has been cultivated for centuries. It is prized for its bright flavor and higher heat level compared to the jalapeño, making it a go-to pepper for fresh Mexican salsas and sauces where a sharper kick is desired.
