PRESERVING FOOD FOR WINTER- Pickled sweet banana & jalapeno peppers

My husband and I have a small garden. We plant aromatics such as rosemary, lavender, mint, thyme, oregano, parsley, and basil; veggies such as peppers, tomatoes, cucumber, and eggplants. This year we also planted Japanese sweet potatoes. They were simply delicious.
Cucumbers were hyper productive this year, so I pickled quite a large quantity. They will be a real treat in the winter.
It's already September and our sweet banana and jalapeno peppers are still producing actively, so today I'm making some pickled banana and jalapeno peppers.
