Shank at 70 degrees: Slow roasting

Lower leg packed with collagen. Hours of moist heat turn it into the sticky, spoonable meat of osso-style braises. Cheap per kilo until restaurants rediscovered it; still one of the best value cuts on the animal. Liquid should come halfway up the shanks. Turn once so both sides glaze.

Buy for size match — two shanks of equal weight cook evenly in one pot. Colour, sinew, where the fat sits, and thickness are what you check before you pay. Ask for the thickness that matches “Slow roasting.” Use 70 degrees and 70 when you cook. Salt after you know the job. Do not play with undercooked meat.

Cook Shank to 70 degrees and serve it as “Slow roasting.” The other figure to watch is 70. Do not time a hard-working muscle like a thin steak. Colour before heat is not doneness. French-trimmed shanks with a clean bone handle look better and brown more evenly. A cut’s grain comes from how much the muscle worked. Shank needs heat through to 70 degrees before “Slow roasting” 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.
