Omasum
Third stomach · bible tripe · センマイ
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.
Black membrane removed, folds sharp and clean. Scrub with coarse salt several times to clear the smell.
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.
Thick wall, white fat clinging inside. Trim too aggressively and the flavour goes with the fat.
