While the noodles are boiling, add the doubanjiang to the mentsuyu.
Add the soy milk and ground sesame and mix well. Then transfer the cooked noodles to a bowl.
Add some water, then the green onions or daikon sprouts, and some stir-fried sesame seeds in ra-yu and it's ready!
Story Behind this Recipe
This is what my father would eat late at night. Normally, I don't add anything heavy to this, but sometimes, I will add something to give it a kick.
The doubanjiang is fairly salty, so this recipe doesn't call for much mentsuyu. In our home, we usually can't consume all the soy milk before the expiration date, so we use the small drink packs for this.
