I made some for the first time for Fourth of July. It wasn’t hard, but I had a little bit of difficulty getting the seeds and ribs out. I was afraid I would split the pepper down the side from the amount of force I was using, but it didn’t happen. I mixed up some cream cheese, some shredded cheddar, and a little mayo to thin it down a bit, then piped the mix into the peppers with my decorating gun and a pastry tip with the widest opening. Then I wrapped them in bacon and tossed them on the grill. I was surprised at how little filling leaked out. I kinda expected a big mess.
***Wear gloves while handling the peppers! You do not want to rub your eye (or any other mucus membrane) even a couple of days later and set your eye on fire. (Happened to me - I had some small amount of jalapeno essence under a fingernail. Yeowch!)
