Is it just me or anyone else? When I try to cook pinto beans (dried beans soaked in water over night) in a cast iron dutch oven on the stove, the beans turn blue in color!!! When I use a regular pot they don't turn blue. What's up with this? Is it just me. BTW, I've tried two different cast iron dutch ovens and they both turned the beans blue.
Thanks for any help.
