On Sunday evening we had our May "Taste-and-Tell" with the Chicago Amateur Bread Bakers. Our focus for this event was cold fermentation of dough (also known as retarded fermentation). We suggested that bakers bring bread whose dough had risen in a cold place--for example, in the fridge, in a basement or unheated entryway, or outside on a chilly day or night.
Bread rises because yeast fermentation is taking place in the dough. The colder the dough, the slower fermentation progresses, and the longer it takes the bread to rise. Slower fermentation may allow more flavor molecules to develop in the dough, which may result in tastier bread. Moreover, dough that has fermented slowly produces bread that stays fresher longer. This is because the long, slow fermentation encourages the yeast to produce lactic and acetic acids, which act as natural preservatives.
Experience with cold fermentation can make one a more versatile bread baker. Getting a feel for how changing the temperature of the dough slows down or speeds up fermentation may help one better control the final bread outcome. One may also begin to develop an awareness of ambient temperature and how it affects the dough. This is especially relevant now, as we move into warmer weather. Lastly, cold fermentation can be a convenient technique to know, when one has a last-minute change of plans and would like to coax the dough to follow one's schedule.
All nine amateur bakers in attendance took up the challenge of experimenting with cold fermentation. To boot, six of the nine participants took a scientific approach, baking two identical batches of bread--and subjecting one of the batches to cold fermentation. We all benefitted from tasting, in turn, a bread made with cold fermentation, followed by the same bread made without. In each case, the former loaf sang with subtle notes of complex sweet and savory flavor, while the latter, in comparison, seemed more simple, perhaps even dull.
