Duck a l'Orange

The skin of the duck breast is scored in a crosshatch pattern and seasoned with salt and pepper, then placed skin-side down in a cold pan before any heat is applied. Starting from cold is the key: as the pan warms gradually to medium-low, the thick layer of subcutaneous fat renders out slowly and evenly, leaving the skin golden and crackling rather than greasy. After flipping and cooking for two to three more minutes, the breast is removed to rest while the sauce is assembled in the same pan. Excess fat is poured off, then sugar and red wine vinegar are cooked together into a dark caramel. Orange juice and zest go in next, and the liquid reduces by half into a glossy sauce with concentrated citrus intensity. A tablespoon of cold butter swirled in at the very end smooths out the acidity and gives the sauce a sheen. Over-reducing the sauce draws out bitterness from the zest, so pulling the pan off heat at the right moment is critical. The rested breast is sliced on the bias and arranged on the plate, with the sauce spooned over and alongside.
