Make the xian dou jiang. Add the shiro-dashi and tofu to the soy milk, and simmer. Please be careful not to bring it to a boil.
When the tofu is heated through, transfer into a bowl. Top with youtiao, dried krill, and green onion, and serve. You can also add ra-yu chili oil and Szechuan pickles.
To make 'Tian Dou Jiang'(sweet milk soup), pour the soy milk in a cup and microwave for 1.5. minutes at 600 W, then add brown sugar or youtaio.
I based this recipe on some dou jiang (soy milk soup) that I had at a famous restaurant in Taipei's "Fu Hang Dou Jiang". It was smooth and easy to drink.
Story Behind this Recipe
There's a famous restaurant in Taipei, "Fu Hang Dou Jiang," which is so popular that there's a large line outside of it even in the morning. Their soy milk breakfast is delicious so I wanted to make it at home. I seasoned it with Japanese dashi so that my husband and kids would like it. I also added tofu to make it more filling.
You can also use Weipa instead of shiro-dashi to give it a Chinese flavor... If you are using thick soy milk, it'll tend to burn in the pot or make a film on the surface easily. It's better to add a little bit of water to thin it out.
