Once properly canned, your Hill Butter will keep indefinitely under appropriate storage.
After opening, your jars of Hill Butter will keep for 6 months, or longer, in the refrigerator; however, I wouldn't be to concerned with this as this is a really tasty spread and probably won't last long.
BY-PASSING THE CANNING PROCESS...if you have people to give your jars to immediately, you don't have to do the canning. You can store your Hill Butter in the fridge and use it up. :o)
Hungarian Wax Peppers are a chili pepper initially grown in Hungary. You may find them in the grocery store being called yellow wax peppers, hot yellow peppers or hot wax peppers. They are not as hot as jalapenos and, to me, have a somewhat sweet taste. They come in several different colors depending on the ripeness...yellow, orange, red and dark red/black. You want the yellow colored ones. They're similar to a banana pepper, but they're not a banana pepper.
