The jelly is not hard to make. Hot pepper jelly can be made from any kind of hot pepper.
I was in Northfield yesterday for the festivities. Ma and I took a tour thru the vendors in the park behind the old high school and found a young lady selling pickles and jellies, most of which were made using hot peppers. I sampled a pickled jalapeno made in a sweet brine that was darned good. I also had some pickled pea pods that had some serious beginnings to heat.
I’m going to pickle all of my Thai-hots and cayenne peppers this afternoon.
