Heart

Heart of Tuna is firm muscle for thin grilling or gentle braising. Mild iron note when fresh. A nose-to-tail piece. As a heart section of offal, portion for even cooking and clear labelling. Keep tuna heart iced until cooking; pat dry for browning, and stop when just opaque (or leave a rare centre on quality loins for steaks and sashimi). Sashimi, searing, canning, and poke suit the cut. Season with salt, acid, and fat that frame dense steak-like muscle.
