Latvian Piragi Recipe

From Wikipedia: Piragi are Latvian oblong or crescent-shaped baked bread rolls or pastries filled with finely chopped fatty bacon cubes and onions. They range from five to thirteen centimeters (2.0 to 5.1 in) in length, depending on if they are intended as a snack or a more substantial meal. Smaller speķrauši are often prized for their daintiness and are considered the work of a skilled cook. Also called:
