A quick summer lunch: Cold Tanuki Udon - refreshing cold udon drizzled in umami mentsuyu and topped with cucumber, tomatoes, tenkasu, wakame, and egg.




  1. Gather all the ingredients. 

    If you are going to/need to make Mentsuyu from scratch, follow the recipe here.

  6. Bring a large pot of water to boil for udon noodles. My favorite udon is the frozen Sanuki Udon. Cook the frozen udon noodles in boiling water for 1 minute (no need to defrost).  If you use dry noodles, follow the package instructions. Remove udon from boiling water and cool in an ice bath. Wait until it cools completely and drain.

  7. To make the sauce, add 1/3 cup of Mentsuyu. My Mentsuyu recipe should be diluted about 2-3 times depending on your preference. If you use store bought mentsuyu, read the directions to see if you can use it “straight” (no need to dilute) or if it should be diluted 2 times or 3 times. Add ice cubes to keep tsuyu cool.
