The jalapeno chile pepper is probably the most well known pepper in the world. The jalapeno pepper originates in Veracruz, Mexico. Most of the U.S. commercial growing of jalapeno peppers is in New Mexico, Texas and Arizona. Jalapenos are used in Mexican and Southwest cooking and are used fresh, canned, smoked and dried. Jalapeno peppers range from 2,500 - 8,000 in Scoville Heat Units (SHU). They are pretty mild; hotter than bell peppers and milder than habanero peppers. Individual peppers can vary in heat also. The smoked form of a jalapeno chile pepper is a chipotle pepper and it rates higher on the Scoville Scale, 5,000-10,000.
Jalapeno flakes are from dried jalapenos that are ground to a small pieces. They are about 1/4" in diameter.
They have no additives, preservatives and are processed in a "sanitary" environment.
