Step 1

Preheat the oven to 400 degrees. Line a small roasting pan (or use a 9X13-inch baking dish) with foil and lightly oil the foil. This is important because the glaze has a high sugar content and will scorch during roasting.

Step 2

Meanwhile, combine 2 tablespoons soy sauce, 2 tablespoons brown sugar, 1/2 tablespoon ginger, 2 teaspoons sesame oil, 2 minced garlic cloves, and 1/4 teaspoon red pepper in a self-sealing plastic bag and mix to dissolve the sugar. Add the pork tenderloins and close the bag. Toss the meat in the bag to coat it with the marinade. Marinade for at least 30 minutes or up to 3 hours.

Step 3

Remove the pork tenderloins from the marinade and place in the roasting pan. Drizzle about half of the marinade over the pork. Discard the remaining marinade. Roast for 15 minutes. Baste the pork with the marinade in the roasting pan. Continue roasting until an instant-read thermometer reads 150-155, about 25 minutes more. The marinade will eventually thicken and scorch, but the foil will protect the pan, so don’t worry. Transfer the pork to a cutting board and let stand for 5 minutes.

Step 4

While the pork is resting, bring the remaining 1 tablespoon soy sauce, 1 tablespoon brown sugar, 1/2 tablespoon ginger, 1 teaspoon sesame oil, 1 minced garlic clove and 1/4 teaspoon red pepper to a boil over high heat in a small saucepan.

Step 5

Cut the roast pork crosswise on a slight diagonal into thin slices and arrange the overlapping slices on a platter. Drizzle the hot marinade over the pork, sprinkle with the scallion, and serve immediately.
