Light crispy tempura is only one half of the puzzle, and this authentic Tempura Sauce Recipe is the perfect blend of umami-rich dashi and seasonings to elevate everything from shrimp tempura to vegetable kakiage.
Add 1 cup dashi, 1 tablespoon soy sauce, 1 tablespoon sake, 1 ½ teaspoons sugar, and 1 teaspoon salt to a pot and bring the mixture to a rolling boil.

Cook the tentsuyu for 1 minute over medium heat or until it no longer smells like alcohol.
For the tentsuyu condiments, peel and grate 300 grams daikon and 20 grams ginger separately. Daikon contains a lot of water, so I recommend lightly draining it so it does not water down your tempura sauce.

Serve the tempura dipping sauce hot with the grated daikon and ginger along with your favorite vegetable or shrimp tempura. If you don't plan to use it right away, store it in an airtight container for up to a week.
