It took me a couple of tries to get close to this and a chat with a Polish baker I bumped into. It is very common in Milwaukee, Wisconsin where I think it traditionally had some boiled potato in it as well. I think it is the best bread for liver pate (liverwurst) or ham or salmon & cream cheese.
I make this in a bread maker, so I add the ingredients in the listed order, then set on the whole wheat bake setting for the medium sized loaf (which is actually considered large).
If you aren’t using a bread-maker, I assume you would:
1 medium sized loaf
10 minutes
2 hours
