The first time I made Boston baked beans in the crockpot, my beans never cooked. We left them in the crockpot for another entire day (!!) - the beans barely softened, but the heat from the crockpot melted the glue between the wood panels in our kitchen table.
The second time I made baked beans I soaked them overnight prior to tossing them in the crockpot. Still no luck.
This time - the third time - I made baked beans, I boiled the beans for all of two minutes in the evening before adding them to the crockpot where they were to cook for the entire next day until dinnertime. Somehow, the beans were already done in the early morning! Boiling them for 2 minutes had more of an impact on the beans than heating them in a high-heat crock pot for 36 hours! I wonder what the science is there...? I'm not a fan of mushy beans, so I need to find a happy medium for attempt #4.
