Forget trying to boil cabbage with potatoes, make your own sauerkraut. Given your history in the kitchen, it would be safer too, as no cooking required, and you are careful slicing the cabbage head! Unless you have a wood stove in the basement by now, it would be an ideal cool place to let the kraut ferment. Like some other fermented foods (natto, kimchi), kraut is an excellent dietary source of vitamin K2.
