Shuck beans are dried 'green beans'. They are a brownish color and very savory when cooked with salt pork. We would string them on strong thread and hang them up to dry...then put them into pillow cases for the winter....usually hanging on the sun porch. My grandfather was from Morgan Co., Ky but his grandparents were from Scott Co., VA.and I assume this dish came from there. My mother said he did something to them with sulfur (smoking, I think), but she doesn't remember exactly what he did. She said she was too busy running after kids to pay attention. It may be the same thing as sulfured fruit, but I don't know what that is. I have a Native American cookbook and this dish is in it(called "leather britches beans"), but no mention of sulfur. My mother says it is the sulfur that gives it the characteristic flavor. Mary msouth@ic.net
