Substituting Peppers

The sugar is mostly just for flavor. I use sugar when making pickled beets and eggs, but don't use it in my dill pickles or pickled peppers and onions. It just depends on if you are trying for a sour, sweet and sour, or sweet pickle (note that there is no vinegar in many fruit pickles).

Before you decide to run off and leave out the vinegar, however, I would note that for pickling safety purposes there has to be enough acid to keep botulism causing bacteria from forming and peppers are a low acid vegetable. If you wanted to eliminate the vinegar, you'd have to move to pressure canning.

I've experimented with growing different varieties of peppers over last decade and found by surrounding one with other types of peppers (sweet, medium or hot) and increasing or reducing water near harvest time you can completely change the heat and flavor of the peppers from that plant. If planted in a pot you can move it around your garden to get different tasting peppers from the same plant throughout the season.
