Recipe Highlights
Ponzu Sauce is one of my favorite condiments to make from scratch. The recipe is flexible, so I reach for whichever citrus looks best when shopping. My method of adding kombu and bonito flakes makes a deeper, more savory sauce than most bottled versions. A jar stays in my fridge to finish dishes with fresh, citrus-infused flavor.
Here’s why I keep coming back to this recipe:
- One sauce for dips, dressings, and marinades
- Make with any citrus you have at home
- Hands-off overnight steeping method
- Keeps in the fridge for up to a month

What is Ponzu Sauce?
Ponzu sauce (ポン酢) is a citrus-based Japanese condiment with a tart, tangy bite close to a light vinaigrette. One origin story traces it to the Dutch pons (citrus juice), brought to Japan during the Edo period, paired with su, the Japanese word for vinegar. Today, ponzu blends citrus juice and vinegar alongside soy sauce and mirin.

How to Make Ponzu Sauce
- Combine everything. Add all ingredients to a sterilized mason jar. Stir well.
- Steep in the fridge. Let the mixture rest in the fridge overnight, or up to a week for a more complex, well-rounded flavor.
- Strain the sauce. Pour it through a sieve, removing the kombu and bonito flakes.
- Bottle and use. Transfer the ponzu to a clean jar with a tight lid. Once strained, it’s ready to use immediately
Nami’s Recipe Tips
Keep these tips in mind for the best results every time.
- Add kombu and bonito flakes – Steep both in the sauce for a deep umami and smokiness that citrus and soy sauce can’t reach on their own.
- Keep it fresh – Always use clean utensils when serving to prevent contamination and extend the shelf life.
- Steep longer for bolder flavor – Overnight works, but a few days to a week gives a more balanced, complex taste—and some restaurants steep theirs for up to a month.
- Save your kombu and bonito flakes. Use leftovers for Homemade Furikake and Kombu Tsukudani so nothing goes to waste.
Make Ahead Tips
- Steep ahead – Ponzu needs at least a night to develop its flavor. For the best flavor, I make mine a few days in advance.
- Double the batch – Ponzu keeps well, so it’s worth making a double batch—especially if you meal prep. Try it in my Japanese Hot Pot Meal Prep.
Storage Tips
To store: Store the ponzu in an airtight jar and refrigerate for up to 1–2 months, if you sanitize your tools and jar during prep.
If you substituted water for the mirin, use it within 1 week.
To freeze: To extend the shelf life even further, freeze it in an ice cube tray for easy portioning.
Variations
This recipe is flexible—here are some ideas to get you started.
- Make it vegan/vegetarian. Swap the bonito flakes for dried shiitake mushrooms for umami depth without the fish.
- Change up the citrus. I use mostly lemon with a splash of orange or grapefruit to balance the tartness. You can also try Japanese citrus like yuzu, sudachi, and kabosu.
- Swap the mirin. Mix sugar with sake for a closer substitute, or with water for an alcohol-free option.
What to Serve with Ponzu Sauce
Ponzu sauce is always a welcome addition to any meal. Here are a few of my favorite ways to use it:
- As a hot pot dipping sauce – The brightness pairs well with any hot pot recipe. I like it with my Mille-Feuille Nabe and Shabu Shabu recipes.
- With sashimi – Flounder (hirame), sea bream (tai), and other delicate white-fleshed fish pair beautifully with ponzu for a lighter, brighter flavor.
- Tuna Tataki – A few drops balance out the rich, seared tuna.
- Tofu Salad with Sesame Ponzu Dressing – A drizzle turns silken tofu into a light, savory salad.
FAQ
What kind of kombu works best?
Any kombu meant for dashi works well. If you plan to reuse the kombu for furikake, ma kombu holds up nicely after steeping. Read my guide to learn more about kombu.
Why is my ponzu too sour?
This usually happens when using lemon juice alone—it can be quite tart on its own. I balance it with a little orange or grapefruit juice to mellow the acidity.
