Japs are supposed to have heat. Period.
I respectively disagree. I grow my own jalepeños, and my favorites not only have heat, but they taste good. The worst jalepeños are bitter. I don't like bitter peppers. A really good jalepeño has the flavor of a banana pepper, or even a bell pepper, but the heat that you want in your salsa or popper.
I have been growing jalepeños for many years, and they are easy to grow, but hard to predict. Sometimes I get lucky, and the peppers are perfect, and sometimes I don't. Last summer was a good summer. I still have a half dozen jars of salsa, and a half dozen jars of pickled peppers.
