Combine ¼ cup soy sauce, 2 tablespoons toasted sesame oil, 2 to 3 cloves crushed garlic, 1 to 2 chopped scallions, 1 ½ teaspoons grated fresh ginger, 1 tablespoon packed light or dark brown sugar, 1 teaspoon toasted sesame seeds, a pinch of freshly ground black pepper, and ¼ cup fresh Asian pear juice or puree (optional) in a small bowl. Mix well. Taste and adjust quantities, if desired.
Use sauce to marinate beef short ribs or slabs of extra-firm tofu (drained and pressed). Place in a shallow dish or zip-top bag and coat evenly with marinade. Marinate for at least 2 hours and up to a day, turning at least once.
