Aji Charapita (Capsicum Chinense)
This small off yellow pepper is the size of a BB. This is a hot pepper with sharp heat. But equally so in flavor. Grows into a small bush that was very high yields.
As the legend or rumors have it. This is supposed to be one of the world's most expensive peppers. It's originally from Peru. And I believe that there might be more story about the most pricey pepper. However, it takes a very long time to get a decent amount of weight picking these. And they are rare in the flavor is incredible.
