Rye bread is a type of bread that is made primarily from rye flour or a combination of rye flour and wheat flour. It is a popular bread choice, particularly in European countries, and is known for its distinctive flavor and dense texture. Rye bread can have a range of variations, from light and mildly flavored to dark and robust. It is often enjoyed for its nutty and slightly sour taste, which comes from the fermentation process involved in making the bread. Rye bread can be sliced and used for sandwiches or served alongside soups and stews.
