When you are just starting out with canning, it can sometimes be confusing as to what foods can be preserved in a water bath canner versus which ones can be canned in a pressure canner.
You can can them as halves or slices. You can add a sugar syrup- or if you don’t want that added processed sugar, you can can them in half water/half juice!
You are probably seeing a theme in these first foods- they are all fruits! Fruits are great for canning in a water bath canner because of their high acid and sugar content.
Pickles are a very acidic food due to all of the vinegar in the recipes.
