The Orange Serrano is a very versatile pepper because of its flavor and medium heat level. The peppers can be pickled and used on sandwiches and salads, or they be used to make salsa and hot sauce. Serrano peppers were originally grown in Mexico and have a medium heat level as they average about 10,000 to 23,000 Scoville Heat Units (SHU). Orange Serranos are hotter than a typical Jalapeno but not quite as hot as a Thai pepper or Habanero pepper. The Orange Serrano is a great pepper for those who want a higher heat level than a Jalapeno, but don't want the spicy heat of a Tabasco pepper or Charleston pepper. The peppers start off green and eventually ripen to orange.
