The technique by which this bread is made has tremendous implications for the baking industry and for both professional and home bakers. The unique delayed-fermentation method, which depends on ice-cold water, releases flavors trapped in flour in a way different from the more traditional twelve-stage method. The final product has a natural sweetness and nutlike character that is distinct from breads made with exactly the same ingredients but fermented by the standard method, even with large percentages of pre-ferment. Also, because the dough is as wet as rustic ciabatta-style dough, it can be used in many ways, from baguettes, as Philippe Gosselin does in Paris, to ciabatta, pugliese, stirato, pain rustique, and even pizza and focaccia. This bread shows us another way to manipulate time, and thus outcomes, by manipulating temperature. The cold mixing and fermentation cycles delay the activation of the yeast until after the amylase enzymes have begun their work of breaking out sugar from the starch. When the dough is brought to room temperature and the yeast wakes up and begins feasting, it feeds on sugars that weren’t there the day before. Because the yeast has converted less of the released sugar to alcohol and carbon dioxide, a reserve of sugar remains in the fermented dough to flavor it and caramelize the crust during the baking cycle. While this delayed-fermentation method doesn’t work for every dough (especially those that are enriched with sugar and other flavor-infusing ingredients), used appropriately, it evokes the fullness of flavor from the wheat beyond any other fermentation method I’ve encountered. As a bonus, and despite all the intimidating science, this is actually one of the easiest doughs in this book to make. Without question this is the dough that has gotten the most recent attention from my students at Johnson & Wales, The California Culinary Academy, and around the country in my daylong workshops for home bakers. It is not just the flavor of the bread that excites them, although without it the concept would be interesting but moot. It is the idea of pressing into new frontiers of bread making, of realizing that there are still areas of exploration not charted by even the professional community. We are learning that as we deconstruct the bread-baking process, we are still in the early discovery stage of what is possible. As in any facet of life, this is an exciting place to find oneself, like standing at the end of the world, facing the words, as so often showed up on ancient maps, “Unknown Kingdoms Be Here.”
Like all rustic doughs, this one requires lots of extra flour, both on your hands and on the counter, in order to handle it.
