Chutoro at 50°: Tuna tartare — Section 1088: Tuna tartare
Section 1088 on Chutoro pairs “Tuna tartare” with benchmark figure 50 (50°) for a grounded decision. Pink flesh with fine white fat lines showing faintly through rather than sitting on top. Cook Chutoro as Tuna tartare to 50° at the centre. Thick grain needs more time. Less cloying than otoro, so it can be eaten piece after piece without tiring the palate.
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. 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 4: check thickness before the clock. 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.

Interactive Scenario & Decision Matrix
Select your current objective to inspect the recommended benchmark, threshold, and verification path.
Use {method}. Stop when you meet this safety line: {safety}.
Briefing 11 for Chuck aligns condition “Braising” with reference value 88 on the ground.
Chuck: 88 (88°)Cook {sub} instead and keep the same safety line: {safety}.
Reading 12 of Chuck uses “Bulgogi” and figure 80 as a checkable baseline.
Chuck: 80 (80°)If you cannot meet {safety}, leave {cut} uncooked.
Atlas note 13 on Chuck defines the operating range of 55 when “Grilling” applies.
Chuck: 55 (55°)Reading 4 of Chuck uses “Pot roast” and figure 88 as a checkable baseline.
Dossier 14 for Chuck links case “Pot roast” directly to metric 88 (88°).
Chuck: 88 (88°)United States (US) Institutional & Field Benchmark
US- Primary reference framework
- English cut names & USDA-style grades
- Verification standard
- Butchery maps + grade stamps
- Metric & unit convention
- Chuck · 88 (88°)
Cut names and grade stamps do not translate 1:1 — shop with local butchery maps.
Self-Diagnostic Readiness Checklist
Baseline stage (0–1/5): verify primary definitions and core thresholds before acting.
5-Step Execution & Verification Playbook
- Name the cut — Confirm {cut} on the sheet.
- Pick doneness — Target {doneness} ~{tempC}°C.
- Pair first method — Lead with {method}.
- Keep safety note — {safety}
- Last-vs-now is a pin — Cook-pair is a bookmark, not a certificate.
Myth vs. Evidence Fact-Check
What temperature does this page recommend for this cut?
The cut sheet already prints {temp} ({tempLabel}) for {name}. That is the published recommendation on this page, not a live thermometer reading.
Which cooking method fits this cut?
This sheet lists {methods} 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: {tempNote} 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.
