Rumen at 60°: Stir-fry

Honeycomb thickness sets the price more than a grade. Cook Rumen as Stir-fry to 60° at the centre. Plate as Grill yang. Angle 3: check thickness before the clock. The first of a cow’s four stomachs, lined with towel-like papillae. The thickest section, sold separately as honeycomb tripe or yanggitmeori, is scarce enough to command a different price. Almost no fat — the whole point is the snap.

Raised, thick papillae mark the premium piece. Thin, flabby sheets are ordinary rumen. Start scored-side down. Overcook and it turns rubbery — flip as soon as the edges begin to curl. Cook Rumen as Stir-fry to 60° at the centre. Thick grain needs more time. A cut’s grain comes from how much the muscle worked. Rumen needs heat through to 60° before “Stir-fry” makes sense. 60 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.
