Prime Graded US  Beef Fillet is cut from the middle of the cow back to the round. This piece of muscle does very little work in the life of the cow so it is some of the most tender cuts of Beef you can get while remaining nice and lean.
 
Known as "the Chefs dream", a piece of Prime Fillet has to be tasted to be fully appreciated.
 
While lean, the Prime grade is only given to the choicest cuts that feature fantastic intramuscular marbling that is just bursting with flavour while maintaining its lean muscle fibers that hold the bite.
Prime graded beef is leagues above Choice graded beef in the US and is some of the finest steak you can buy.
