Cook sequence from this cut sheet
Follow published Omasum — teaching, not a thermometer app.
Name the cut — Confirm Omasum on the sheet.
Pick doneness — Target Medium rare ~57°C.
Pair first method — Lead with Raw beef dishes.
Keep safety note — Heat collapses the folds fast. Even a blanch is only a few seconds in boiling water.
Last-vs-now is a pin — Cook-pair is a bookmark, not a certificate.
Omasum: Medium rare (57°C) via Raw beef dishes.

Substitute cut and safety stop
After the cook sequence for Omasum, a second sheet pass: published swap cut plus the safety line already on this page.
Name the printed substitute — If Omasum is missing at the counter, the sheet points to related cut Rumen — 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 Raw beef dishes.
Hard stop on safety — Heat collapses the folds fast. Even a blanch is only a few seconds in boiling water.
Keep cook-pair as a pin — Saving a cook-pair bookmarks this sheet; it is not a food-safety certificate.
Omasum → swap toward Rumen; 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 or flash-blanched (Heat toughens it) for Omasum. That is the published recommendation on this page, not a live thermometer reading.
Which cooking method fits this cut?
This sheet lists Raw beef dishes · Stir-fry · Frying 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: Heat collapses the folds fast. Even a blanch is only a few seconds in boiling water. 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.

Hundreds of thin leaf-like folds stacked like a book — the third stomach. That geometry shreds into a unique chew, and with almost no fat it is the lowest-calorie cut in this atlas. Most often eaten raw with sesame-oil dipping sauce.
