I have stored beans and peas for many years, and not had a problem..I only soak for 24 and then slow cook up to 8 hrs I do add butter. Sound like something you don't need to mess with..Think about the electricity cost, Lesson learned with that brand.. I don't spice until maybe 2 hrs before eating..Meat and onions I will add when I start the slow cook. Good luck with your endeavor!
