Oyster at 92 degrees: Butcher's treat roast · 556

Two coin-sized nuggets sitting in hollows on the back, either side of the spine. They are the most tender and best-flavoured meat on the entire bird and there are only two per chicken, which is why the French name translates roughly as "the fool leaves it there". Turn a roasted chicken over before carving and scoop them out with a spoon — they are hidden from above.

They cook in place while the bird roasts; the only skill involved is remembering to go looking for them afterwards. Colour, sinew, where the fat sits, and thickness are what you check before you pay. Ask for the thickness that matches “Butcher's treat roast.” Use 92 degrees and 92 when you cook. Salt after you know the job. Do not play with undercooked meat.

At the counter, read the use on Oyster before the photograph. 92 degrees is the internal heat, “Butcher's treat roast” is the dish, and 92 is the stage of the fire. Marbling alone does not split stew from grill. Tiny yield per bird — freshness and careful butchery matter far more than any stamp.
