Just wondering, does cream of tartar go bad? I'm one of these people who date their baking powder and baking soda and throw it out after 6 months.
I only use cream of tartar to make snickerdoodles and once in awhile to beat egg whites. I've had my bottle since I got married and I'm not sure I should still be using the stuff! If it stopped working a long time ago I never noticed. Any thoughts?
