Confit is one of the oldest preservation techniques in French cuisine — submerging meat in its own rendered fat and cooking it low and slow until the collagen breaks down into silk. Here, that tradition meets the umami depth of white miso in a cure that penetrates the duck legs over 24 hours before they ever meet heat.
The result is duck that falls from the bone, carries a faint sweetness from the miso, and shatters into a crackling crisp when you blast the skin in a hot pan. Serve over soft polenta or alongside pickled daikon for a study in contrasts.
