Rye flour, dark

Dark rye flour is the whole-grain, higher-bran version of rye flour, used most often in dense, dark breads like German pumpernickel, Scandinavian rugbrod, and traditional Jewish rye. Because rye has less gluten-forming protein than wheat, doughs made with it are typically mixed with a portion of wheat flour or leavened with a sourdough starter to get a good rise, and the resulting loaves have a moist, tight crumb and a slightly sour, earthy flavor that pairs well with caraway seeds, cured fish, and strong cheeses. It is also used in small amounts in crackers, pancakes, and some cookie doughs, where it adds a deeper, more rustic flavor than all-purpose flour.

Store dark rye flour in an airtight container in a cool pantry, or in the freezer for longer keeping, since its higher oil content from the bran and germ can turn rancid faster than refined flour. At 325 calories and 15.9 grams of protein per 100 grams, it is a dense baking ingredient rather than a light one, and it stands out for fiber, delivering 85% of the daily value alongside 28% for iron and 38% for magnesium, making a loaf built around it a meaningfully fiber-rich alternative to white bread. Its low sugar content, 2.31 g per 100 g, also means most of its flavor complexity comes from fermentation rather than sweetness.
