I've noticed that when I use baking soda in recipes...they taste very bitter to me. Dh and the kids don't seem to mind, though dh says he can tell there's a difference between BS pancakes and BSfree pancakes. I'm wondering if its just not good for me right now? Or could it actually be slightly off? (In other words...should I bother buying new baking soda, or has anyone noticed a similar issue? Maybe its because I'm having trouble with acids, so there's nothing to temper it?)
