My latest King Arthur mailing has a recipe for Icelandic Rye Bread (Rugbraud). It's online at
https://www.kingarthurbaking.com/rec...ugbraud-recipe. In the photo, the bread appears to be sliced thin.
Many of King Arthur's lovely recipes feature one of their products, in this case calling for their organic medium rye flour, but I usually have good results substituting something close if I don't want to order the exact thing from them.
