Ingredients for Roasted oysters with warm butter mignonette

  • 1 small shallot, finely chopped

  • 45 ml red wine vinegar

  • 12 oysters in shell

  • coarse sea salt or kosher salt

  • 60 g unsalted butter, melted

How to make Roasted oysters with warm butter mignonette

  1. Preheat the oven to 200°C (fan oven 180°C).

  2. Stir the shallot, vinegar, and 15 ml of water in a small bowl; set aside.

  3. Line a plate with salt to help hold the oysters in place without spilling their juices, and set aside.

  4. Rinse the oysters, then arrange them flat side up on a wire rack set inside a rimmed baking tray.

  5. Roast the oysters for 4–6 minutes, until they crack open slightly. (They will not open completely like cooked clams; the top shell will separate from the bottom, creating about a 1 cm opening at the rounded end.) Some oysters may open before others—remove them from the oven as soon as they open. Discard any oysters that do not open after 7 minutes.

  6. To finish opening the oysters: Fold a dish towel several times and hold the oyster using the towel.

  7. Slide a butter knife into the opening all the way to the hinge.

  8. Turn the butter knife perpendicular to pop the top shell open completely.

  9. Carefully pull off the top shell by hand, ensuring not to tip the bottom shell and lose any liquid. This should occur easily without much force.

  10. Gently slide the knife under the oyster in the bottom shell to release the muscle, then transfer it to the plate with salt.

  11. Stir the butter into the reserved vinegar mixture and spoon it over the oysters.
