⅓ cup low-sodium soy sauce
5 garlic cloves, peeled and crushed
1 (1-inch) piece fresh ginger, peeled and thinly sliced
2 scallions, cut into 1-inch pieces, plus more thinly sliced scallions for garnish
2 tablespoons neutral oil, such as safflower or canola
2 tablespoons turbinado or light brown sugar
½ teaspoon black pepper
1 (14- to 16-ounce) block firm tofu, drained and cut into 1-inch cubes
6 ounces fresh shiitake mushrooms, stemmed and sliced into ½-inch-thick pieces
Steamed rice and kimchi (optional), for serving
In a 12-inch nonstick skillet over medium heat, combine soy sauce, garlic, ginger, scallions, oil, sugar, pepper and ¼ cup water; mix well. Add tofu and mushrooms, season with salt and bring to a simmer. Reduce heat to medium-low and cook, carefully turning tofu and stirring occasionally, until sauce thickens into a glaze and coats the mixture, about 15 minutes.
Transfer the jorim to a serving bowl or platter and garnish with thinly sliced scallions. Serve with rice and kimchi, if using.
