Wonderful 100% Rye Sourdough Crumb
Last month I've been playing with pure 100% sourdough rye bread formulas.
From the last loaf one of best crumb (the receipt was published on my blog, LINK). A super moisty, very open crumb. This is even closer to the one I've seen in Torino (Andrea Perino's Bakery), but that was a 90% rye and I don't know if they add also a bit of fresh yeast.
