"have you considered adding a pinch of cream of tartar (potassium bitartrate) instead?"
yes, but I have not done so... need to research a bit more.
"Curious to know your thoughts on cream of tartar..."
I am likely to give it a try at some point. The bottom line is I will have to try it before I can know what, if anything it will do for me.
I do like the idea of moving away from the chloride a bit more... I have, for the most part decreased my redmonds salt intake dramatically in the last several months and would like to reduce the little potassium chloride I consume as well.
