Rumen

First stomach · honeycomb tripe · ミノ

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.

High heat, briefSurface only

Raised, thick papillae mark the premium piece. Thin, flabby sheets are ordinary rumen.

Abomasum
Lucarelli · Public domain

Abomasum

Fourth stomach · reed tripe · ギアラ

The true acid stomach — and nothing like pork makchang, which is the end of the large intestine. A thick wall with fat layered inside: grilled, the outside stays chewy while fat bursts from within. A whole animal yields only about half a kilo.

Medium heat, patientCooked through

Thick wall, white fat clinging inside. Trim too aggressively and the flavour goes with the fat.
