If you want a softer jalapeño popper, you can par boil the jalapeño pepper before stuffing them. We don't do this. First, it's extra steps. We like this because it's an easy appetizer, and once you start adding more steps, it's not as easy any more. We also don't par boil the peppers because the creamy tuna stuffing is already really soft. So the crunch from the jalapeño peppers are a great contrast to the soft filling. If everything was soft and squishy, it just wouldn't be that great of a bite.
