Savory xian dou jiang with vinegar, dried shrimp, and scallion is a unique soy milk breakfast. A protein-rich, fresh family recipe with tangy umami flavor.
Add the unsweetened soy milk to a saucepan and gently warm over medium heat, stirring occasionally to prevent scorching. Do not let it boil.
While the soy milk warms, soak the dried shrimp in hot water for 5 minutes, then drain and chop finely.
Cut the soft tofu into bite-sized cubes and thinly slice the scallions.
In a small bowl, combine Chinese black vinegar, light soy sauce, sesame oil, white pepper, and salt to form the seasoning mixture.
Once the soy milk is hot (steaming but not boiling), gently add tofu cubes and chopped shrimp. Simmer for 2 minutes, keeping the heat low.
Turn off the heat and stir in the seasoning mixture. Gently ladle the soup into bowls.
Top each serving with sliced scallions and pieces of Chinese fried dough stick for texture. Serve immediately while hot.
