Step 1
Toast soybeans in a dry skillet over medium heat, stirring constantly, until fragrant and lightly golden, about 5 minutes.
Step 2
Add 1 cup water to soybeans. Bring to a boil, then reduce heat and simmer until soybeans are very tender, about 12 minutes.
Step 3
Pour soybeans and cooking liquid into a blender. Add 2 cups cold water, soy sauce, sesame oil, and salt.
Step 4
Blend on high until completely smooth and creamy, about 1 minute. Transfer to a bowl and refrigerate for at least 10 minutes.
Step 5
Boil noodles in salted water until tender, about 4 minutes. Drain and rinse under cold running water until cool.
Step 6
Divide cold noodles between two bowls. Pour chilled soy broth over noodles until nearly full.
