About
Duck breast is a dense, iron-rich poultry cut that weighs about 7.9 ounces (225 g) per standard cup.
Duck breast has a typical bulk density of roughly 59.3 pounds per cubic foot (0.95 g/mL). Because of its firm muscle tissue and exterior layer of fat, diced pieces sit relatively compact in a measuring cup. At 7.9 ounces (225 g) per US cup, it is slightly less dense than liquid water. Its weight by volume closely mirrors other rich poultry cuts and boneless pork.
From Wikipedia
In cooking and gastronomy, duck or duckling is the meat of any of several species of bird in the family Anatidae, found in both fresh and salt water. It is found in domestic and wild forms and is a very calorie dense food, containing high fat, protein, and iron.
