Great idea on the potato! I used frozen beans. They have a nice flavor and a good lima green color.
My mother would never use green limas except as a side dish. But maybe I've misunderstood? I was thinking you were making this as a main dish.
Dried lima beans soaked overnight, then basically stewed with ham hocks and broth, with diced potatoes added--that would have been a main dish. Before crock pots were invented, my mother would have done all this on the stove. Later she would have used a crock pot. Of course she cooked the ham hocks first, to make the broth. Then she would have removed the meat from the bones and added it to the beans and potatoes.
Ham hocks, bacon, molasses, brown sugar, and I-don't-know-what-all else is the way cooks where I come from would make homemade baked beans (unfortunately no bourbon). The difference would be that they would use dried lima beans--soaked overnight, of course. Maybe that's a Central Pennsylvania thing.
The funny thing is, this is also basically the way she made bean soup. She just would have used dried navy (?) beans instead. (Except for lima beans and kidney beans, I'm a little vague on bean types.
)
