What is ponzu made of?

Ponzu is a citrus-based sauce commonly used in Japanese cuisine. It adds a tangy, savory flavor to foods like fish, meat, vegetables, and more. But what exactly goes into this versatile condiment? Here’s a look at the main ingredients that make up ponzu sauce.

Key Ponzu Ingredients

While there are many variations, authentic ponzu sauce is generally made with just a few key ingredients:

  • Soy sauce – The base of ponzu is soy sauce, which contributes savoriness, saltiness, and depth of flavor.
  • Rice vinegar or lemon juice – Ponzu gets its bright, citrusy flavor from rice vinegar or fresh lemon juice.
  • Mirin – Mirin is a sweet Japanese rice wine that balances out ponzu’s acidity.
  • Dashi stock – Dashi, made from kombu (dried kelp) and katsuobushi (dried bonito flakes), adds savory umami flavor.
  • Citrus juice – Freshly squeezed juice from yuzu, sudachi, lime, or other citrus brightens up the ponzu.

By blending soy sauce, vinegar, mirin, dashi and citrus, you get a sauce that hits all the flavor notes – salty, sweet, sour, and umami. The inclusion of citrus juice gives ponzu its name – “pon” means to mix, and “zu” refers to vinegar.

Ponzu Variations

While those ingredients form the base of ponzu, there are many variations on the classic recipe. Some common ponzu tweaks include:

  • Fruit juices – Lemon, lime, grapefruit, orange, or other fruit juices can be used in place of or in addition to rice vinegar.
  • Citrus zests – Grated yuzu, lemon or other citrus zest adds fresh, aromatic flavors.
  • Other vinegars – Vinegars like rice wine, champagne, red wine, or white wine vinegar can supplement or replace rice vinegar.
  • Additional seasonings – Ingredients like sesame oil, garlic, ginger, herbs, spices, chilies, and more can customize the ponzu flavor.
  • Vegetable brochette ponzu – Some ponzu recipes add pureed onions, carrots, mushrooms, or other vegetables for flavor and texture.

There are also many store-bought bottled ponzu sauces that offer unique ingredient twists. Some contain fruits like yuzu, lemon, or orange, while others might have additions like bonito, konbu, ginger, or garlic.

How is Ponzu Traditionally Made?

Authentic ponzu starts with a base of soy sauce and rice vinegar or fresh citrus juice. Here is a simplified overview of the traditional ponzu production process:

  1. Brew and ferment soy sauce from soybeans, wheat, salt, and water.
  2. Make or acquire rice vinegar or freshly squeeze citrus juice like yuzu, sudachi, or other citrus.
  3. Prepare dashi stock by infusing kombu kelp and katsuobushi flakes in water.
  4. Gently heat and combine the soy sauce, vinegar/citrus, dashi stock, and mirin in specific proportions.
  5. Allow the ponzu to age for 1-3 months to develop the flavors.
  6. Before using, strain the ponzu to remove any sediment.

Traditional artisanal ponzu is made through time-honored methods to produce a beautifully balanced, umami-rich sauce. However, there are some quick ponzu shortcut recipes that don’t require brewing soy sauce or dashi from scratch.

Ponzu Ingredients Breakdown

Now let’s take a more detailed look at the key ingredients that go into ponzu and what each one contributes.

Soy Sauce

Soy sauce is the base ingredient of ponzu, making up about 50-70% of the final product. Japanese ponzu uses tamari soy sauce, a gluten free variety made with just soybeans, salt, and water. The soy sauce provides:

  • Savoriness
  • Saltiness
  • Umami flavor
  • Rich, thick texture

Quality and type of soy sauce has a big impact on the final ponzu flavor. Higher quality, naturally brewed soy sauce gives a deeper, more complex flavor.

Rice Vinegar

Rice vinegar makes up around 20-30% of ponzu’s ingredients. It contributes:

  • Bright, tangy acidity
  • Slight sweetness
  • Helps balance out soy sauce’s saltiness

High quality rice vinegar has a mild, pure flavor that won’t overpower the other ingredients. Second choice is apple cider vinegar or white wine vinegar.


Mirin is a sweet Japanese rice wine used in small amounts, around 5-10% of ponzu total. It adds:

  • Sweetness to balance acidity of vinegar
  • Slight alcohol flavor
  • Helps mellow and round out flavors

Get authentic hon-mirin or taka-mirin variety. Or substitute a mix of sake and sugar.

Dashi Stock

Dashi is a savory Japanese stock made from kombu seaweed and katsuobushi (dried bonito flakes). It makes up around 5-10% of ponzu. Dashi contributes:

  • Rich, savory umami flavor
  • Subtle ocean flavors from the seaweed and fish
  • Mouthfeel and body

Use dashi sparingly as it can overwhelm other flavors. A high quality instant dashi powder can substitute.

Citrus Juice

Fresh-squeezed yuzu, sudachi, lemon, lime or other citrus juice makes up around 5-15% of ponzu. It provides:

  • Bright, fresh acidity
  • Bold citrus flavors
  • Helps cut richness of soy sauce

Yuzu is traditional but any citrus works. Mixing a few juices creates nice complexity.


Some ponzu recipes also include a small amount of water, generally around 5-10%. The water helps thin out the texture and modulate the strength of the flavors.

Ponzu Nutrition Facts

As a mixture of several ingredients, ponzu sauce has a nutritional profile that reflects its components:

Nutrient Amount

How to Use Ponzu Sauce

Ponzu sauce is extremely versatile in the kitchen. Here are some of the many ways it can be used:

  • Sashimi and sushi – Mix with freshly grated ginger and daikon to make a tangy dipping sauce for raw fish.
  • Fish – Brush on salmon, tuna, halibut or other fish before broiling or grilling.
  • Meat – Use as a marinade or dressing for chicken, pork, or steak.
  • Vegetables – Toss ponzu with cucumbers, edamame, mushrooms, asparagus, or greens.
  • Salad dressings – Whisk with oil and sesame for a bright citrus vinaigrette.
  • Noodles – Toss Japanese soba or udon noodles with ponzu and scallions.
  • Dumplings and potstickers – Mix ponzu with soy sauce for a dipping sauce.
  • Rice bowls – Drizzle over rice along with sesame seeds, scallions, and chili oil.

Ponzu’s savory-sour flavor profile works well on nearly any food. Try experimenting with it in stir fries, roasted vegetables, tacos, egg dishes, and more for a pop of flavor.

Substitutes for Ponzu

Don’t have ponzu in your pantry? Here are some potential substitute options:

  • Lemon/lime juice + lower sodium soy sauce – Approximates ponzu’s sour citrus + savory profile.
  • Rice wine vinegar + lime juice + dashi/bouillon – Mimics the rice vinegar, citrus, umami of ponzu.
  • Orange juice + lime juice + fish sauce – Provides citrus flavors and savory saltiness.
  • White wine vinegar + lemon zest + dash soy sauce – Gives acidity, citrus, and light soy notes.

While the complex flavor of ponzu is hard to duplicate exactly, combining citrus juice for acidity with a savory element like soy sauce or fish sauce can get you close in a pinch.

Where to Buy Ponzu

Wondering where you can purchase ponzu sauce? Here are some places to find it:

  • Asian grocery stores – Check the international aisle of Asian supermarkets, which carry many Japanese ponzu brands.
  • Online – Many specialty Japanese food sites sell ponzu sauce that can be shipped to your home.
  • Amazon – Look for popular ponzu brands like Kikkoman, Yamasa, Marukin, and Mitsukan on Amazon.
  • Large supermarkets – Some well-stocked mainstream grocers carry ponzu, often Kikkoman brand.
  • Japanese restaurants – Ask if they sell bottles of the ponzu sauce served with their sushi.

When buying ponzu, look for brands imported from Japan for authentic flavor. Check the ingredients to get the type you prefer, like yuzu ponzu or dashi ponzu. Once opened, store ponzu in the refrigerator.

Common Questions

Is ponzu sauce gluten free?

Most ponzu is gluten free, as it is made with tamari soy sauce rather than traditional soy sauce that contains wheat. But check labels to be sure, as some brands may use regular soy sauce or other ingredients with gluten.

How long does homemade ponzu last?

Homemade ponzu will keep for 1-2 months stored in an airtight container in the refrigerator. The flavor may start to degrade after that time. For longer shelf life, store ponzu in the freezer for up to 6 months.

What’s the difference between ponzu and yuzu kosho?

Yuzu kosho is a spicy Japanese condiment paste made from yuzu zest, chili peppers, and salt. Ponzu contains yuzu juice for tangy flavor, but also has soy sauce, vinegar, mirin, and dashi. While they both include yuzu, they are very different condiments.

Can I substitute Meyer lemon for yuzu?

Yes, Meyer lemon juice or zest can be used in place of yuzu’s hard-to-find juice or zest. Meyer lemon has a sweeter, less acidic flavor that approximates elusive yuzu citrus. Regular lemon also works.


With its salty-sweet-sour-umami flavor profile, ponzu is a uniquely Japanese condiment that enhances all kinds of foods. Anchored by a tamari soy sauce base, ponzu gains its signature bright taste from rice vinegar and fresh citrus like yuzu or lemon. Aromatic ingredients like mirin, dashi, ginger, and scallions round out ponzu’s complex flavor. Use ponzu anywhere you want to add a pop of savory-tangy flavor – seafood, meat, noodles, rice, vegetables, and more will all benefit from a splash of this versatile sauce. Though store-bought bottled ponzu abounds, you can also easily whip up homemade ponzu in minutes with just a few pantry ingredients. Once you try it, the possibilities for ponzu will seem endless.
