Tenderloin at 70 degrees: Poaching · 543

Pull the white tendon out before cooking by gripping it and scraping the meat back with a knife; it never softens. It is thin enough that residual heat alone can finish it — pull it from the pan the moment it turns opaque. The small strip lying under the breast, attached along a tough white tendon. It is the most tender muscle on the bird and cooks in a fraction of the time, which is why it is the natural candidate for skewers, goujons and a lightly seared sashimi in Japan.

Colour, sinew, where the fat sits, and thickness are what you check before you pay. Ask for the thickness that matches “Poaching.” Use 70 degrees and 70 when you cook. Salt after you know the job. Do not play with undercooked meat. Cook Tenderloin to 70 degrees and serve it as “Poaching.” The other figure to watch is 70. Do not time a hard-working muscle like a thin steak. Colour before heat is not doneness. Should be small, even strips with no tendon sheath left attached after trimming.

Cook Tenderloin to 70 degrees and serve it as “Poaching.” The other figure to watch is 70. Do not time a hard-working muscle like a thin steak. Colour before heat is not doneness. Should be small, even strips with no tendon sheath left attached after trimming. A cut’s grain comes from how much the muscle worked. Tenderloin needs heat through to 70 degrees before “Poaching” makes sense. 70 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.
