Chutoro at 50°: Tuna tartare

Pink flesh with fine white fat lines showing faintly through rather than sitting on top. Less cloying than otoro, so it can be eaten piece after piece without tiring the palate. Mid-fat belly; grade talk is really about boat and handling. Cook Chutoro as Tataki to 50° at the centre. Plate as Tuna tartare. Angle 2: check thickness before the clock.

The meeting point between the savour of the lean loin and the fat of the belly. If otoro is spectacle, chutoro is balance — which is why it usually anchors a course rather than closing it. Cook Chutoro as Tuna tartare to 50° at the centre. Thick grain needs more time. A cut’s grain comes from how much the muscle worked. Chutoro needs heat through to 50° before “Tuna tartare” makes sense. 50 is a stage of that heat, not a luxury score. The same cut becomes a stew, a grill, or a braise, so a steak minute does not cover a pot. Thick connective tissue wants time, not a hard sear alone. This is not medical advice.
