Definition: The word "Leicaaarau" refers to a type of bread that is popular in many parts of Switzerland, particularly in the canton of Uri. It's known for its light, fluffy texture and unique taste. The bread's origin can be traced back to 19th century Switzerland, when it was invented by a baker named Jean-Louis Leica. The term "Leicaaarau" is used figuratively to refer to any kind of loaf or baguette that is lighter in texture and flavor than regular bread. It's often used synonymously with the Swiss Loaf, which is another type of flatbread popular throughout Switzerland. This type of bread is known for its unique shape and baked in a tube-like shape, making it easier to digest.
