About this cut

The Fraldinha is a fan-shaped cut from the bottom sirloin, celebrated in Brazilian churrascaria culture for its deep marbling and rustic, coarse-grained texture. It sits at the intersection of the flank and the loin, offering a unique combination of lean, beefy muscle and melting fat pockets. When prepared correctly, it provides an explosion of savory juices and a bite that is satisfyingly substantial without being tough. This is an aficionado's cut, prized for its intense flavor over sheer tenderness.

Cooking Guide

Grill the Fraldinha over intense, direct heat to develop a heavy Maillard crust, aiming for a medium-rare core temperature of 52-54°C. Avoid overcooking, as the coarse fibers can become dry and stringy beyond medium. Resting for at least 10 minutes is critical to allow the internal juices to redistribute; once rested, it must be sliced thinly against the grain to ensure a tender mouthfeel.

Pair with a robust Touriga Nacional from Portugal or a high-altitude Malbec, as the high tannin levels and dark fruit profiles perfectly cut through the charred fat and mineral-rich beef.
