What is Tempura Dipping Sauce?

Tempura dipping sauce, also known as tentsuyu, is a traditional Japanese sauce that is served in a small bowl with tempura dishes. In fact, I have never ordered tempura at a Japanese restaurant and had it not served with tempura dipping sauce. The salty flavor of the sauce is the perfect complement to the savory flavor of the tempura batter.

What Ingredients are Used to Make Tentsuyu (Tempura Dipping Sauce)?

The three main ingredients that make up tempura dipping sauce (tentsuyu) are dashi, mirin and soy sauce. Many chefs also add grated daikon radish or a little bit of sugar to their dipping sauce to cut the saltiness.

Made from bonito fish flakes and kelp (kombu), dashi is a popular Japanese soup base that serves as the primary base for tempura dipping sauce (tentsuyu). This ingredient provides the umami flavor that you expect from tempura dipping sauce. You can make your own dashi or use a dashi soup packet that is mixed with water.

Mirin is a sweet Japanese cooking wine used in a wide range of dishes from sauces and glazes to savory meals. In tempura dipping sauce, mirin adds a slightly sweet element to your sauce.

Soy Sauce

A staple for many Japanese sauces and dishes, soy sauce needs no introduction. Soy sauce provides the salty flavor that tempura dipping sauce is known for.

Daikon radish is a popular ingredient in Japanese cuisine and the main component in oshinko. It provides a refreshing and slightly pepper flavor and a slightly crunchy texture when added to your tempura dipping sauce. If you do add, make sure you squeeze the water out prior to grating. I also grate the daikon directly into the bowl of sauce immediately prior to serving to ensure it is fresh.
