I bought a grocery store package of dried mixed beans for soup once since it was cheaper to get bean seeds for the garden than buying them in separate little packages in the garden department. After picking out a few for the garden, I cooked up the rest. Same thing happened - mud and nasty tasting. The included spices were even worse. Can’t believe the grocery store could sell much of this.
Well I’m glad I wasn’t alone in that coming out so horrible..it really was not eatable....and totally banished forever my desire for bean soup!
