It's been a long time that i've wanted to try this (from Reinharts BBA).
The recipe asked for a small portion of pumpernickel grind flour, but i can't find that, so i used a small percentage of wholewheat.

Couronne crease/ cracks didn't came out so well thanks to not making it deep enough. Flavour was great! Tasted mildly sour and of toasted sunflowers.
