IR 64 Parboiled (5-25%) Broken is a type of rice that has been partially boiled in the husk, which results in a firmer and drier grain. The "IR" in the name refers to the Indian Rice variety, while the "64" refers to the size and quality of the grain. The "(5-25%) Broken" part of the name indicates that the rice grains are broken, but they are still edible and can be used in a variety of dishes.
