A cartouche is a round piece of baking parchment placed directly over food or liquid to reduce evaporation during gentle cooking.
Professional Method
Cut parchment slightly larger than the inside diameter of the pan, fold it into a wedge, trim the radius, then unfold. A small centre vent can be cut when controlled steam release is useful. Lay the paper directly on the food or liquid surface.
Why It Works
A cartouche limits direct surface evaporation without sealing as tightly as a conventional lid. It is useful when ingredients should remain moist while still allowing some reduction and visual access.
Applications
Use for braised vegetables, shallow poaching, fruit compotes, glazed vegetables and preparations where exposed surfaces could dry before the interior cooks.
Control Points and Common Mistakes
Keep parchment away from open flame and heating elements. Use baking parchment rated for the cooking temperature, not waxed paper. Replace torn or heavily soiled paper.
Chef’s Note
Use visual, tactile and temperature cues together. A technique is successful when it improves control of the finished food, not merely when the procedural steps have been completed.
