Pickled Banana or Hungarian Peppers from Kerr canning book @ 1966
Thoroughly wash peppers. Make a small slit in each one in two places. Put the peppers in a brine made of 1 gal. water to 2 cups of salt. Weight to hold peppers under brine. Next day, drain well and pack peppers into sterilized KERR jars. Make a pickling solution of 1 gal. of water, 1 cup of salt, 1 cup vinegar, 1 garlic clove, 1 grape leaf and 1 bunch of dill. Bring the solution to the boiling point, pour over peppers in jars, filling and sealing one jar at a time with the boiling solution.
**I believe that 1 tsp alum can be used in place of the grape leaf as that is the source of alum (grape leaves).
I use put vinegar 5% acidity in my peppers and then water bath them for 20 minutes, I think. If you have a Ball Blue book you can see how long it is for pints and quarts to water bath them.
I also put them in bread and butter pickle mix to make what is called Cowboy Candy. Yum.
