Rack at 80 degrees: Rack with mustard crust · 393

The rib section frenched into a curved rack — the showpiece cut. Short fibres and a fat cap make it forgiving on high heat, which is why tasting menus and holiday tables both reach for it. Expensive because each animal only yields two small racks. Frenched bones should be clean and even; a thick, creamy fat cap is a feature, not waste.

Often sold as 'spring lamb' when under a year — milder and smaller than hogget. Colour, sinew, where the fat sits, and thickness are what you check before you pay. Ask for the thickness that matches “Rack with mustard crust.” Use 80 degrees and 80 when you cook. Salt after you know the job. Do not play with undercooked meat.

Cook Rack to 80 degrees and serve it as “Rack with mustard crust.” The other figure to watch is 80. Do not time a hard-working muscle like a thin steak. Colour before heat is not doneness. Rest ten minutes after roasting so the juices settle between the bones. A cut’s grain comes from how much the muscle worked. Rack needs heat through to 80 degrees before “Rack with mustard crust” makes sense. 80 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.
