Correct Answer: Sirloin

The sirloin is the most tender wholesale cut of the beef carcass. The tenderloin (filet mignon / psoas major), which is the most tender individual muscle, lies within the sirloin region.

Why is Sirloin/Tenderloin the Most Tender?

• The psoas major muscle (tenderloin) is located deep in the loin area, under the lumbar vertebrae.
• It does minimal work during the animal's life (supports but does not bear weight or move much) → very few connective tissue cross-links → ultra-tender.
• Low collagen content → no need for moist heat cooking → best prepared by dry heat methods (grilling, pan-frying).
