Now, let’s walk through the steps to create this incredible Shrimp Tempura Udon Soup:

1. Prepare the Broth: In a large pot, bring the dashi broth to a gentle simmer. Add soy sauce, mirin, and sesame oil for flavor.
2. Cook the Udon: In a separate pot, cook the udon noodles according to the package instructions. Drain and set aside.
3. Prepare Tempura Batter: In a bowl, mix the tempura batter mix with cold water according to package instructions until smooth.
4. Heat Oil: In a deep skillet or pot, heat vegetable oil over medium heat until it reaches about 350°F (175°C).
