Heart at 66 degrees: Stir-fry

Choose pieces trimmed of blood clots and white tendon, with a surface that is not slimy. Cook it through and it goes chalky. Best when the outside has colour and the centre is still faintly pink. Specialty organ — freshness and trim beat any stamp. A cut’s grain comes from how much the muscle worked. Heart needs heat through to 66 degrees before “Stir-fry” makes sense. 66 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.

Colour, sinew, where the fat sits, and thickness are what you check before you pay. Ask for the thickness that matches “Stir-fry.” Use 66 degrees and 66 when you cook. Salt after you know the job. Do not play with undercooked meat. At the counter, read the use on Heart before the photograph. 66 degrees is the internal heat, “Stir-fry” is the dish, and 66 is the stage of the fire. Marbling alone does not split stew from grill. A muscle that never rests, fine-grained and firm, with almost none of the off-notes that put people off other organs. Low in fat and frank in chew, it eats closer to a dense steak than to classic offal — which is why it
