Homemade ponzu sauce is a bright, citrusy Japanese soy-based sauce made with soy sauce, fresh lemon and lime juice, and kombu for deep umami flavor. It’s mixed together in 5 minutes and ready to use. The flavor is light, salty, and perfectly balanced. I use it as a dipping sauce, quick marinade, or easy dressing for noodles, seafood, and vegetables.
Ponzu sauce is pretty readily available at the store, but I have all these ingredients at home already, so whipping it up is so easy. Plus, I think the fresh citrus juice adds so much more complexity and flavor. I just stir together soy sauce, rice vinegar, mirin, lemon, and lime juice, then let a piece of kombu sit in the jar to infuse everything with that deep, savory umami. It only takes a few minutes to prep, and the flavor gets even better as it chills. I use it all the time for dipping dumplings or egg rolls, drizzling over salmon or rice bowls, or tossing with noodles when I want something quick but really flavorful.
Tips for Beginners
- Use fresh citrus juice for the best flavor. I’ve tested this with bottled juice, and it just doesn’t compare. Fresh lemon and lime juice give the sauce a brighter, cleaner flavor and better balance overall.
- Give it time to infuse. Don’t skip the resting time. I like to let the kombu infuse for at least 3 hours, but overnight gives the best flavor. Just be sure to remove it within 24 hours to avoid any bitterness.
- Remove the kombu at the right time. Once it’s done infusing, take the kombu out. Leaving it in too long can start to give the sauce a slightly bitter or overly strong flavor.
- Adjust the balance to your taste. This is an easy sauce to tweak. If it tastes too sharp, add a small splash of mirin to round it out. If it’s too salty, squeeze in a bit more citrus to brighten it up.

Becky’s Tips
- Add a touch of sweetness: A splash of orange juice gives the sauce a slightly sweeter, more rounded citrus flavor.
- Use it as a marinade: This works beautifully as a quick marinade for chicken, fish, or tofu.
- Add some heat if you like: Sprinkle in a pinch of chili flakes for a subtle kick.

How to Make Ponzu Sauce Step by Step
Gather all the ingredients together.
Combine the base ingredients: Add ½ cup soy sauce, 1½ tbsp rice vinegar, 1½ tbsp mirin, the juice of 1 lemon, and the juice of 1 large (or 2 small) limes to a mason jar and stir until everything is fully combined and smells bright and citrusy. Drop in one 2×2-inch piece of kombu, making sure it’s fully submerged, then seal the jar with a lid.
Let the sauce infuse: Place the jar in the refrigerator and let it sit for at least 3 hours so the flavors can infuse and deepen.
Serve and enjoy: When you’re ready to use it, remove and discard the kombu. The sauce should taste balanced, citrusy, and slightly savory. Serve as a dipping sauce for egg rolls, dumplings, sushi, or fish, or drizzle over noodles, salads, or lettuce wraps for a quick boost of flavor.
How to Store and Reheat
Store ponzu sauce in an airtight container or sealed mason jar in the refrigerator for up to 1 week. I like to give it a quick stir or shake before using since the citrus and soy can settle slightly over time. For the best flavor, remove the kombu after the initial soak and keep the sauce chilled until ready to use. Freezing isn’t recommended, as the fresh citrus flavor can become dull once thawed.
Serving Suggestions
I love using this ponzu sauce as a dipping sauce for crispy chicken potstickers since the bright citrus cuts through the richness perfectly. It’s also a go-to with egg rolls, adding a light, tangy contrast to the crunchy exterior. For something a little more elevated, I’ll drizzle it over seared or grilled salmon, where the salty, citrusy flavor pairs so well with the richness of the fish. I also like to spoon it over chicken lettuce wraps for a light, fresh finish that adds just the right amount of flavor.
