1 teaspoon turmeric
2 teaspoons kosher salt
1/2 teaspoon pepper
2 14-ounce containers extra-firm tofu cut into 1-inch cubes and patted dry
2 cored-and-quartered plum tomatoes
1 chopped shallot
stems from 1 bunch cilantro (reserve the leaves)
1 tablespoon fish sauce or soy sauce
1 tablespoon chili-garlic sauce
3 stalks lemon grass, trimmed to the lower 5 inches (dry outer layers discarded and thinly sliced) and
1/4 cup neutral oil
14-ounce can coconut milk
1 teaspoon salt
1/2 teaspoon pepper
2 diced tomatoes
steamed jasmine rice for serving
In a medium bowl, stir together 1 teaspoon turmeric, 2 teaspoons kosher salt and ½ teaspoon pepper. Add two 14-ounce containers extra-firm tofu (cut into 1-inch cubes and patted dry) and toss. Set aside.
In a blender, combine 2 cored-and-quartered plum tomatoes, 1 chopped shallot, the stems from 1 bunch cilantro (reserve the leaves) and 1 tablespoon each fish sauce and chili-garlic sauce. Blend until finely chopped, about 30 seconds.
Add 3 stalks lemon grass, trimmed to the lower 5 inches (dry outer layers discarded and thinly sliced) and blend, scraping the blender jar frequently, until a smooth, thick paste forms, about 90 seconds. Set aside.
In a 12-inch nonstick skillet over medium-high, heat 1/4 cup neutral oil until shimmering. Add the tofu in an even layer and cook without stirring until well browned on the bottoms and the pieces release easily from the pan, about 3 minutes. Using a spatula, turn the pieces and cook until browned on all sides, another 7 to 9 minutes. Transfer to a large paper towel–lined plate.
Return the skillet to medium-high. Add the tomato–lemon grass paste and cook, stirring, until slightly darkened and thickened, 2 to 3 minutes.
Stir in one 14-ounce can coconut milk, 1 teaspoon salt, 1/2 teaspoon pepper and 2 diced tomatoes. Bring to a simmer then cover, reduce to low and cook until the tomatoes soften, about 5 minutes.
Add the tofu and stir to coat. Cover and simmer, stirring occasionally, until the tofu has absorbed some of the sauce, about 10 minutes. Stir in and sprinkle with reserved cilantro leaves before serving.
