Is there any hope for these hard baked beans?

[Lilymax]

You guys always have such great cooking advice, I thought it was worth asking...

 

I followed a crock pot baked bean recipe on the back of a bag of dry navy beans. Soaked 'em overnight and everything. They smelled so good cooking today, but when I went to test them after 8 hours, they were still hard as rocks!

 

So...I Googled it. Should've done that first! I found out that adding salt or acidic ingredients before the beans are soft makes them stay hard. The recipe called for ketchup, molasses, mustard and salt and said to put it all in together at once.

 

I added another cup of water, and thought I'd try letting them cook a while longer, maybe overnight. Do you think they'll eventually get soft or should I just count it as a loss?

 

Thanks!
