The discovery of the jalapeno pepper dates back to the Ancient Aztecs, however, they weren’t popularized until the late 1400s. Jalapenos go by the scientific name Capsicum annuum ‘Jalapeño’. Though jalapenos are mostly cultivated in parts of Mexico such as Jalapa and Chihuahua, this spicy, green pepper is now grown all over the world. In the US, jalapenos are cultivated in Southwestern states such as New Mexico, Texas, and California. Furthermore, jalapenos, which grow in hot weather, are a popular garden vegetable harvested in the summer. 

When ripe, jalapenos can measure between two and three inches in length and about an inch in diameter. Though they’re typically harvested when they reach a deep green hue, if they’re given the time to fully ripen, they actually turn a deep red in color. Jalapenos have a taste similar to green pepper, however, they’re much spicier. Jalapenos can be enjoyed raw or cooked, but the small white seeds pack tons of heat; so if you’re looking for a milder flavor, simply scoop the seeds out. 

Jalapenos are a staple in Mexican cooking and they can be found in popular recipes for salsa, pickled jalapenos, stuffed jalapenos, and chiles toreados. In American cooking, popular jalapeno recipes include jalapeno poppers, jalapeno scones, jalapeno cornbread, and spicy queso. A great source of dietary fiber, phosphorous, and magnesium as well as vitamins C and B6, jalapenos are a nutrient-rich addition to a well-rounded diet. What’s more, routine consumption of jalapeno peppers is said to aid in weight loss, help fight cancer, prevent bacterial growth, and ward off the common cold with their high antioxidant count.
