Not sure about battering them, but we make them by halving the peppers, scooping out the seeds, filling it with a cream cheese mixture and wrapping it firmly in bacon.
Believe it a not I found this in an Amish Cookbook. It's very simple. Cut jalepenos in half and take out seeds. In a plastic sandwich bag put cream cheese and your favorite shredded cheddar or other shredded cheese. Mix by massaging the bag. Sqeeze all the cheese mixture to one corner of the bag. Cut off a corner and flute the cheese mixture into the jalepenos. Wrap each pepper with a half slice of bacon and secure with a pick. Bake or grill until the bacon is cooked and crisp and jalepeno cooked and cheese melted. Enjoy!
Wow! Excellent ideas, all! DH was super hungry, so I ended up making a cream cheese/steak seasoning filling for the split and deseeded peppers and wrapping them in a foil packet, then putting them on the grill. Forgot to Pam the foil, so they ended up losing their skins, but all in all they were pretty good.
More jalapenos are on the list! Just gotta try some of these ideas!
