My husband loves jalepeno peppers. One year we planted quite a few and I canned them for him. Not an experience I ever repeated.
The canning recipe I used called for garlic, onion, horseradish and vinegar. It was so potent and stinky, it gagged me and made my eyes water. I had to go outside while it simmered. Then, being a know-it-all, I didn't wear gloves like the recipe stated while I cut little slits in the peppers. My hands sizzled for quite a while after that. :o
However, he loved the peppers.
