Cook sequence from this cut sheet
Follow published Otoro — teaching, not a thermometer app.
Name the cut — Confirm Otoro on the sheet.
Pick doneness — Target Medium rare ~57°C.
Pair first method — Lead with Sushi.
Keep safety note — Straight from the fridge it stays mute; a few minutes out and the fat opens up completely.
Last-vs-now is a pin — Cook-pair is a bookmark, not a certificate.

Substitute cut and safety stop
After the cook sequence for Otoro, a second sheet pass: published swap cut plus the safety line already on this page.
Name the printed substitute — If Otoro is missing at the counter, the sheet points to related cut Chutoro — same atlas, not inventing a new primal.
Check shared method fit — Prefer a published method that still fits the substitute; lead method on this sheet is Sushi.
Hard stop on safety — Straight from the fridge it stays mute; a few minutes out and the fat opens up completely.
Keep cook-pair as a pin — Saving a cook-pair bookmarks this sheet; it is not a food-safety certificate.
Otoro → swap toward Chutoro; stop on the printed safety line before plating.

Doneness and method on this cut
What temperature does this page recommend for this cut?
The cut sheet already prints Raw (5 min at room temperature) for Otoro. That is the published recommendation on this page, not a live thermometer reading.
Which cooking method fits this cut?
This sheet lists Sushi · Lightly seared with fitness scores. Pair one of those methods with a doneness from the published scale (Blue 46 C through Well done 77 C). The cook-pair block pins last versus now — teaching, not a diagnosis.
Can I serve this cut pink?
Follow the sheet note already on this page: Straight from the fridge it stays mute; a few minutes out and the fat opens up completely. Connective-tissue cuts ask for time; tender steaks ask for a rest after the published temp. The safety note at the bottom still applies.
Is the doneness scale a food-safety certificate?
No. The pair tool and the recommended temp are teaching numbers from this atlas. Use the printed sheet and your own thermometer. This page is not a medical or hygiene certificate.

The forward belly, and the summit of tuna fat. Everything this cut is worth comes down to a fat density that starts melting the moment it meets body temperature.
