I’d go with unsalted butter in the long term, if you’re worried about too much sodium in your soil.

Burning a scrap of printed paper will reveal any copper content as a bright green color in the flame. Paraffin itself is very pure.

Another way to make the tortillas is to use yeast instead of baking powder, and let it sit for 30-60 minutes after mixing to let it rise before rolling it out.
