Cinnamon raisin swirl. No tunnels.
Thank you all but especially @teonzo. I used the egg wash not quite as suggested. I brushed it on the topside of the dough with each turn as I rolled it up. I also doubled both the smear and the raisins.
Cold proofing in the refrigerator are two 500 g boules of the Compleat Wheat. I am hoping I have been successful in evenly distributing the toasted wheat bran and germ.
Edited to add that my eight dollar thrift store electric knife is doing a fine job. So far I still have five fingers on each hand but I do understand @JoNorvelleWalker‘s reluctance to use it on hard bread. I do believe that the team recommend not approaching it from the (top) crust side but tipping it so you are not attempting to saw through the crust head on. Yes. Photograph on page 3–424 demonstrates how to approach the bread with electric knife in hand. This is further demonstrated on page 3–426 for non-electric knives.
