  "key": "Cartouche",
  "value": "A disc of greaseproof paper laid directly on the surface of a simmering liquid, cut to the width of the pan with a small hole in the centre. It slows evaporation while still letting steam escape, so a braise or poach stays submerged and cooks evenly without the liquid reducing too far. Less enclosing than a lid, and easy to cut from a folded square."
