Interesting. If one wasn't making _walnut_ bread but still wanted to tint any bread, other sources of tannins would work, right? So adding a little bit of an iron supplement tablet to some brewed tea, for example, should have the same effect? Or soaked grape or oak leaves, or crabapple juice, etc.?
Stiv - I had the same thought as I was writing this, and it's one I haven't got an answer for yet. I need to see what happens when you add iron to various tannin containing extracts. Will let you know when I do!
very cool! i have tried for purple loaves twice-- with green tea and black tea as two different tannin sources. dough was a greyish blue, and the loaf similar, definitely not a crimson like your amazing image. the reaction of tannin&iron in the water was a dark purple, as in your photos (to my eye). curious why blue not more reddish? i added the tannin-iron liquid to porridge loaves, since i am trying to learn their ways...too many variables? fats in the butter? or maybe not enough iron in my reaction liquid?
wondering also about how the dough in a formula dictates the form it bakes in -- your porridge loaves are intended for loaf pans, as opposed to shaping into ...boules or something else. is that a best form/shape/process for that formula?
i made "porridge boules" and great, but there was a thick wettish layer below the upper crust. could be all sorts reasons on my end besides shape! but

the answer is yes - any tannins will do. I just added a tiny amount to some green tea, and it turned purple instantly.
Thanks! I figured it would but still nice to get experimental confirmation!
So cool! I loved that purple loaf when I first saw it.

just curious, in general, about that
cheers!
