Sear the SteaksHeat vegetable oil in a skillet over high heat. Season steaks with salt and pepper. Sear on all sides until your preferred doneness. Let rest.
Prepare the SauceIn a saucepan, add shallots, port, and Madeira. Carefully ignite to burn off alcohol. Reduce by half. Add the reduced stock and simmer until thickened. Strain out solids. Stir in truffle essence and finely chopped fresh truffle. Remove from heat and whisk in cold butter until glossy. Keep warm.
Build the CroûtesSpread each croûte with liver pâté and chopped truffle. Shape sautéed spinach with a round cutter slightly larger than the croûte and place it beneath the croûte.
Prepare the VegetablesSauté the baby Jersey Royals in goose fat until golden. Lightly sauté the asparagus heads. Glaze the carrot cubes in a mixture of orange juice and chicken stock until shiny and tender.
Assemble the DishPlace the spinach-lined croûte on the plate. Top with the rested steak. Spoon over the truffle sauce. Add a small dollop of pâté, garnish with sliced truffle, and top with a touch of edible gold leaf.
Serve ImmediatelyPresent hot with vegetables arranged artistically around the plate.
