Serrano pepper's distinctive flavor makes it the most popular pepper along the Mexican border. It is a favorite for salsas, sauces, stews, and soups. Serranos are definitely hot peppers with a good kick and are not for the faint of palate (but, they are not as hot as Thai, Ghost or Habanero peppers). Small, finger-shaped, hot peppers picked green or red. Use fresh or dry for future use and for your own killer chile powder. Maturity 75 Days. Approx 23,000 Scoville heat units.
