A dipping sauce made especially for tempura, tentsuyu directly translates to "heaven soup"!

Tentsuyu is a dipping sauce for tempura. Tsuyu actually means soup, but usually refers to dipping sauce – mentsuyu for noodles and tentsuyu for tempura.

The biggest difference between mentsuyu and tentsuyu is the ratio of the main ingredients, namely soy sauce, mirin and dashi. We like a ratio of 1:1:5 for tentsuyu, although you should experiment to find out what you prefer!

You might like to add grated daikon to your tentsuyu. It brings an enjoyably slushy texture and adds just a touch of sharpness to the taste of your dipping sauce. Daikon also helps digestion and relieves heartburn, which can be a bonus for fried foods like tempura.
