Here is Grandpa's udon with raw egg and tororo potato. He had to have Tsuyu Soy Sauce to make this, so we went to a Japanese grocery to buy it. I would be able to replicate Tsuyu Shoyu pretty easily by mixing up Soy Sauce, Mirin and Dashi powder, but for Grandpa,s cocking, he needs to have all the specified things on the recipe. He even MEASURES everything (which I never do)! It was delicious.
