Note 1: Every batch of beans our family has ever made cooks differently! Sometimes, if left too long in the oven, they can turn to mush. If not left long enough, they’re watery and still tough-skinned. It’s a matter of watching them very carefully after the first 1.5 hours, so be sure to allow enough time :)
Note 2: if you don't have a bean pot, simply use a crock-pot. After soaking and pre-cooking the beans, toss all the ingredients into a crock-pot and set to about 8 hours. Keep an eye on them to ensure there's still enough liquid in the pot. If they start looking dry, simply add more bean water.
