Sweet pickles for home canning I want to substitute some natural cane sugar for white sugar, because I don't have enough of the white to make pickle recipe. The recipe calls for 7 cups of sugar, and I have 4 1/2 of refined white sugar so I want to use the rest in natural cane sugar. Will this work?
Yes, you should be fine with a mixture of sugars as it is mostly for flavoring. The main point is to make sure the sweetener is fully dissolved in your pickling liquid. 

One user asked a similar question about using honey, and searching the web also produced recipes for how to use sugar substitutes in place of sugar for pickling.
