  • When frothy, add the beef and sear on both sides. Cook 2 minutes per side. The beef will be rare.
  • Remove beef from pan to a grid.

For the mashed potatoes:

  • Peel the potatoes and cut into 3 cm cubes then rinse in cold water to remove the excess starch.

  • Strain then pass through a food mill back into the same pan.
  • Add the butter, little by little and whisk briskly.
  • Add the cold milk in the end to loosen up the mashed potatoes.
  • Season with salt and pepper.
  • Serve the chateaubriands warm and cover in the creamy pepper sauce. Serve the mashed potatoes on the side in a small dutch oven.
