Prior to the twentieth century the Red Jalapeno was most commonly sold at the market in its dried and smoked form. This pepper has a conical shape and comes to a broad end at its tip. Its shiny red skin is smooth and usually marked with characteristic striations known as “corking”. As a matter of fact, the crisp flesh of this pepper is slightly sweeter than the immature green jalapeno and has a notably hotter spice. Besides, Red Jalapeno peppers can be used interchangeably in recipes that call for green jalapenos. It is worth noting that the heat in peppers, which is caused by capsaicin, clears the sinuses. It even helps to fight sinus infections by cleansing the airways. This means you can literally breathe easier with the help of jalapeño peppers.
