If you are looking for an authentic Tentsuyu (tempura dipping sauce) recipe like the ones served at Japanese tempura restaurants, I highly recommend giving mine a try! It strikes a delicate balance of sweet and savory flavors that complement the tempura without overwhelming the natural taste of the ingredients.

Instructions
In a small pot, combine all the ingredients (dashi stock, mirin, and soy sauce) and heat over medium heat. Once it reaches a simmer, reduce the heat to low and let it cook for about 30 seconds.
Let the seasoning liquid cool to around 105-140℉ (40-60℃), then pour it into serving bowls. Optionally, serve it with grated daikon or ginger on the side.
Notes
You can store it in the refrigerator for up to 3 days.
