How to Make It
In a bowl, whisk the mushroom soy sauce with the honey and curry powder. Score the top and bottom of the beef tenderloins in a crosshatch pattern about 1/2 inch deep. Transfer the tenderloins to 2 large resealable plastic bags and pour in the marinade. Turn the tenderloins to coat with the marinade, seal the bags and refrigerate overnight.
Preheat the oven to 500°. Transfer the tenderloins and the marinade to a large rimmed baking sheet. Rub the tops of the tenderloins with the vegetable oil. Roast the tenderloins in the upper third of the oven, basting every 8 to 10 minutes, for about 30 minutes, until an instant-read thermometer inserted in the thickest part of the roasts registers 125° for medium-rare. Transfer the tenderloins to a carving board and let rest for 10 minutes. Slice the tenderloins and serve warm or at room temperature.
