1 porterhouse steak, about 1.5–2 lb (680–907 g) (1.5–2 inches thick) 2 tsp kosher salt 1 tsp freshly ground black pepper 1 tbsp neutral oil 3 egg yolks 1 / 4 cup (60 ml) white wine vinegar 2 tbsp (30 ml) dry white wine or water 1 small shallot, minced 1 tbsp chopped fresh tarragon, plus more to finish 8 tbsp / 1 stick (113 g) unsalted butter, melted and warm Pinch of black or white pepper Lemon juice, to taste
1. In a small saucepan, simmer vinegar, wine/water, shallot, and half the tarragon until reduced to 2 tablespoons. Strain; cool slightly. 2. Whisk yolks with the warm reduction over a barely simmering bain-marie until thick and creamy. 3. Slowly drizzle in warm melted butter while whisking to emulsify. Season with lemon juice, salt, and pepper; fold in remaining tarragon. Keep warm. 4. Pat steak dry; season with salt and pepper. 5. Heat oil in a heavy skillet over high; sear steak 3–4 minutes per side. Reduce heat and cook to desired doneness (120–125°F for medium-rare). 6. Rest 8–10 minutes. Slice and serve with generous spoonfuls of Béarnaise.
