With this loaf, Seattle-based baker Doughy Tribbiani wished his readers a "Happy Challa-ween". It's a beautiful bread that illustrates what amazing sculptures can be made with challah dough. He colored it with activated charcoal.
How does Tribbiani get this coloration in his sourdough? It's a baking style called "pane incamiciato", which means "bread in a jacket." Here's a YouTube video that illustrates the technique.
Tribbiani isn't completely happy with this Valentine's Day sourdough, but I think that it's wonderful. It's a pane incamiciato, but not fully opened. Just the heart pokes through.
