Final answer:
Mastros uses prime corn-fed beef because it is high quality, has more marbling for better flavor and tenderness, and offers a consistent taste due to a controlled feeding regimen.
Step-by-step explanation:
Mastros uses abundantly prime corn-fed beef because it is considered to be of high quality and has certain advantages.
Firstly, corn-fed beef tends to have more marbling, which refers to the white streaks of fat within the meat. This marbling enhances the flavor, tenderness, and juiciness of the beef.
Additionally, corn-fed beef is known for its consistent and predictable taste. The corn-based diet provides a uniform and controlled feeding regimen, resulting in beef with a reliably good taste.
