Chef's Tips

• Bring the steak to room temperature before cooking for even doneness.

• Use a meat thermometer:

  • 125°F (52°C) – Rare

  • 135°F (57°C) – Medium-Rare

  • 145°F (63°C) – Medium

• Let the steak rest before slicing to keep it juicy.

• Warm the cream before adding it to the mashed potatoes for a smoother texture.

• Roast the garlic before mashing for a sweeter, deeper flavor.
