Oxtail at 95 degrees: KKOMAGUK

Choose thick joints with a cross-section where the marrow fills the bone completely. Joints should be evenly cut; grade rarely printed — buy on fat and smell. Every joint of the tail concentrates gelatin and marrow. That is why a long-simmered oxtail broth turns milky white rather than staying clear — it is emulsified collagen, not fat.

Colour, sinew, where the fat sits, and thickness are what you check before you pay. Ask for the thickness that matches “KKOMAGUK.” Use 95 degrees and 95 when you cook. Salt after you know the job. Do not play with undercooked meat. Cook Oxtail to 95 degrees and serve it as “KKOMAGUK.” The other figure to watch is 95. Do not time a hard-working muscle like a thin steak. Colour before heat is not doneness. The finish line is when the marrow has fully surrendered and the broth has gone opaque.

The finish line is when the marrow has fully surrendered and the broth has gone opaque. A cut’s grain comes from how much the muscle worked. Oxtail needs heat through to 95 degrees before “KKOMAGUK” makes sense. 95 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.
