    When you order Tempura at a restaurant, you’d be given a small dish of dipping sauce on the side to enjoy with. Casually known as Tempura Dipping Sauce, we also call the sauce Tentsuyu (天つゆ).

    The sauce is light and refreshing and it can magically uplift the deliciousness of tempura in an instant. With just a handful of pantry ingredients, you can make it in less than 5 minutes!

    4 Ingredients You’ll Need for Tempura Dipping Sauce

    While making tempura at home may be more fitting for a weekend cooking, the dipping sauce is unbelievably easy to whip up. Simply measure out the ingredients, whisk them together and you’re good to go.

    Here are what you need:

    1. Dashi

    This is the foundation of Japanese flavor. Delicate yet complex, dashi (Japanese soup stock) is an absolute must for the dipping sauce.

    You can choose to make dashi from scratch (I almost always keep a mason jar of previously cooked dashi in my refrigerator for all my Japanese recipes) or use the convenient dashi powder or dashi packet to make dashi instantly.

    2. Soy sauce

    The salty, savory, and umami-rich soy sauce does much of the heavy lifting of the overall flavor. Use gluten-free soy sauce for Gluten-Free Tempura.

    3. Mirin

    This Japanese sweet rice wine adds a mild sweetness and luster to the sauce.

    4. Sugar

    Just a touch of sugar balances out the saltiness, and round up the dipping sauce with the best result! Adjust the amount according to your taste.

    With a little balancing act, you’ll get a dipping sauce that complements and elevates your crispy juicy tempura!

    The Short-Cut Version

    As a back-up when I run out of dashi or want to save time, I use store-bought Mentsuyu to prepare Tempura Dipping Sauce.

    Made with sake, mirin, soy sauce, kombu, and dried bonito flakes, Mentsuyu is the base sauce used in many Japanese noodle dishes and dipping sauces.

    Mentsuyu is typically concentrated and you’ll need to add water to dilute it.

    For Tempura Dipping Sauce (See the Japanese word 天つゆ), you will need to combine 1 part of Mentsuyu and 3 or 4 parts water. Taste it and adjust the flavor according to your taste. I often add a splash of mirin when I use Mentsuyu.

    You can find a bottle of Mentsuyu at Japanese/Asian grocery stores or online on Amazon.
