Does anyone have any tips/advice how to soften up their northern/navy beans before or while cooking them in baked beans recipes? This last batch I let soak for 3 days in the frig before cooking them. I've been cooking them in the crockpot for 12 hours and they are still firm. I'm not sure of the temp in the crockpot but the beans cook at a steady boil. I've also tried in the past with little or no success to soak them for a few days then freeze them in hope of breaking any seed coat keeping the moisture from penetrating the bean. Thanks in advance for any advice/tips. PS While soaking and cooking I make sure the beans are always overtopped by water.
