Pumpernickel is a type of dark, dense bread made primarily from coarsely ground rye flour. It originated in Germany and is known for its rich, slightly sweet flavor and chewy texture. Traditionally, pumpernickel is baked slowly at low temperatures, which gives it its characteristic dark color and unique taste. This bread is often enjoyed with various toppings, such as butter, cheese, or cured meats. It is also a popular choice for sandwiches and can be found in many bakeries and grocery stores. Pumpernickel is considered a healthy option due to its high fiber content and whole grain ingredients.
