Made these loaves the other day. I thought you might enjoy looking at them. It’s a recipe that I came up with during the pandemic lockdown. If the hydration level is too challenging, I suggest bring it down 10%. It’s very soft. Makes great toast.
Enjoy.

Looks interesting, do you have a photo of the crumb?
