This blueprint is the result of rigorous engineering experiments designed to produce a repeatable, perfect sourdough cinnamon bread loaf with superior volume and clearly defined interior spirals.
The structural integrity of the crumb is best appreciated when the bread is handled with care after it leaves the oven; slicing too early allows steam to escape prematurely, compressing the internal crumb structure. If you wish to deviate, substitute the 1.5 tablespoons of cinnamon entirely with 1.5 tablespoons of ground cardamom for a Cardamom Swirl Variation. For storage, keep the loaf in a paper bag for the first 24 hours to preserve the crust's crispness.
