What Is Rye Flour?
Rye flour is flour milled from whole rye berries and grains of rye grass. Closely related to wheat flour, it has a slightly sour taste and is used to prepare rye bread and sourdough bread. Loaves of bread produced with rye flour are generally darker and denser than other types of bread. Rye and sourdough breads have a distinctive flavor that are enjoyed by many. Sauerkraut and corned beef are especially good on sourdough bread, and rye bread is a good substitute for white bread for just about any sandwich.
