Make the Pimento Crust Toast the pimento and peppercorns until fragrant, then grind them. Mix with paprika, garlic powder, onion powder, salt, and brown sugar. Press this mixture firmly onto the steaks. Pro Tip: The crust should look like a deep, warm bark—never dusty or loose.
Crisp the Thyme Potatoes Parboil the potatoes until just tender. Pan‑fry in butter + oil with thyme sprigs until the cut sides turn golden and crisp. Cue: They should sound like tiny applause in the pan.
Sear the Steak Heat a cast‑iron pan until very hot. Sear the steaks 2–3 minutes per side. Add butter, thyme, and garlic, then baste. Target Temps: Medium‑rare: 128–130°F Medium: 135°F Rest 8–10 minutes.
Make the Rum‑Peppercorn Pan Sauce Using the same pan: Toast crushed peppercorns. Add Wray & Nephew and reduce until syrupy. Add beef stock and reduce by half. Stir in cream, Dijon, and Worcestershire. Simmer until glossy. Optional Chef’s Touch: Add 1–2 drops of Rivers rum right before serving for a lifted, aromatic finish.
