Yesterday I wanted to make navy bean soup in the crock pot. Picked and rinsed the beans. Soaked in boiling water for about 1/2 hour. Drained and put in the crock pot with an onion, 2 carrots, 2 celery stalks and 2 bay leaves. Hot water to cover. Turned the crock pot to low and returned 7 hours later. Beans still crunchy. OK, so then I poured them into a dutch oven and cranked up the heat on the stove top. Dinner time came and went. I finally turned off the stove at 9:30 last night and the beans were still very firm.
Beans were new - just bought them at Sunflower Market on Monday and I didn't use any salt. What do you think happened?
