This is so refreshing with grated daikon radish! This tentsuyu is so great, you'll want to eat a lot of tempura to go with it! Goes well with rice, too!
Pepper, salt and soy sauce are also delicious, but for tempura, you just gotta have tentsuyu!
I happened to be out of usukuchi light soy sauce, so the picture actually shows it made with dark soy sauce. The real thing should be a bit lighter.
Enjoy Japanese food around the world.
