These poppers will be mildly spicy. For more heat, don’t remove all of the jalapeño seeds and leave the membranes intact.
Add a little more flavor to the filling with some chopped fresh parsley or cilantro.
When handling jalapeños and other hot chiles, wear plastic gloves. The oils that get on your hands will stay there, so if you were to rub your eyes after touching the chiles, you could really hurt yourself! You can buy powder-free gloves at a pharmacy.
