En papillote (wrapped in parchment paper or baking paper or foil) is a popular way to cook fish, seafood and vegetables, so the ingredients bake and steam at the same time, while keeping in all the flavour and moisture while using little or no fat.
Food (nearly always seafood or fish) prepared en transparence is similar, but cooked in a see-through material. It’s often the method used in restaurants, as it allows the chef to see what’s happening and is more attractive than burnt paper and aluminium when served.
