Crispy Glazed Tofu with Bok Choy for Two

Fold a clean kitchen towel in half and place it on a cutting board. Set the tofu on the towel. Put another folded towel and a weight (such as a heavy skillet) on the tofu; let drain for 15 minutes.

Meanwhile, whisk plum sauce, ketchup, soy sauce and rice wine in a small bowl and place near the stove.

Cut the pressed tofu into 3/4-inch cubes and place near the stove.

Heat 1 teaspoon oil in a medium cast-iron or nonstick skillet over medium-high heat. Add scallion, garlic and ginger; cook, stirring, for 30 seconds. Add bok choy and cook, turning, until bright green, 1 to 2 minutes. Add water, cover and steam until tender, about 2 minutes. Transfer everything to a plate. Wipe the pan dry.

Return the pan to medium-high heat, add the remaining 1 1/2 teaspoons oil and heat until shimmering. Add the tofu in a single layer. Cook, without stirring, until starting to brown on the bottom, 2 to 3 minutes. Stir and continue cooking, stirring frequently, until brown on all sides, 6 to 8 minutes more. Add the reserved sauce and cook, stirring gently, until the tofu is well coated, 1 to 2 minutes. Serve with the bok choy, sprinkled with sesame seeds.
