Mikuni White Sauce Recipe: Sushi Bar Creamy Elegance

This velvety white sauce brings sushi bar elegance to your kitchen with minimal effort.

With just a few ingredients, you’ll create a creamy, rich sauce perfect for drizzling over rolls or dipping tempura.

Ingredients for Mikuni White Sauce

Eight simple ingredients craft that signature velvety sushi bar sauce you crave at home.

The mayonnaise and sour cream are doing the heavy lifting here. Duke’s or Hellmann’s for mayo—skip the low-fat versions, they won’t emulsify right. Sour cream from Breakstone’s or Daisy has the right tang. For rice vinegar, Kikkoman or Nakano are easy to find at most supermarkets. Don’t confuse this with regular vinegar; the mild acidity is key for balance.

No rice vinegar? Apple cider vinegar at half the amount works in a pinch. Want it thicker? Add another spoon of mayo. For a lighter version, Greek yogurt can replace half the sour cream, but it’ll be tangier. Skip the garlic powder? Fresh minced garlic at half the quantity does the trick. The soy sauce adds umami—tamari works too for gluten-free.

This keeps beautifully in the fridge for up to 10 days. Store in an airtight container. If it separates, just whisk it back together. Doubles easily—make extra and drizzle on everything from fries to salmon.

Step-by-Step Instructions for Mikuni White Sauce

Here’s the method that brings that signature sushi bar creaminess to life in minutes.

Step 1: Combine the Creamy Base

In a medium mixing bowl, whisk together the 0.75 cup Mayonnaise and 0.25 cup Sour Cream until completely smooth. I use full-fat versions for that ultra-rich texture—this is what gives the sauce its luxurious body.

You’ll notice the mixture thickens slightly as you whisk. That’s exactly what we want. The mayonnaise provides the creamy foundation while the sour cream adds a subtle tang that balances the richness perfectly.

Step 2: Sweeten and Acidify the Mixture

Add the 1 tbsp Sugar and 1 tbsp Rice Vinegar to the bowl. The sugar might seem like a lot, but it’s essential for that authentic sushi bar flavor profile. Whisk vigorously for 30 seconds until the sugar dissolves completely.

Here’s the thing—the rice vinegar adds a gentle acidity that cuts through the richness without being noticeable. It’s the secret to making this sauce taste balanced rather than cloying. You won’t taste the vinegar, but you’ll miss it if it’s not there.

Step 3: Add Umami and Seasonings

Stir in the 1 tsp Soy Sauce, 0.5 tsp Garlic Powder, and 0.5 tsp Onion Powder. The soy sauce adds depth and umami without making the sauce taste Asian—it just enhances all the other flavors.

I always use low-sodium soy sauce here to keep the salt level in check. The garlic and onion powders provide a subtle savory backdrop that complements the creaminess. Whisk until all the spices are fully incorporated and the sauce looks uniform.

Step 4: Finish with White Pepper

Finally, add the 0.25 tsp Ground White Pepper and whisk one last time. White pepper has a milder, more earthy heat than black pepper, and it’s the traditional choice for this sauce. It should be barely perceptible—just a whisper of warmth in the background.

The sauce should now be smooth, creamy, and pale off-white in color. Give it a taste and adjust if needed, though I find this ratio perfect. The texture should coat the back of a spoon with a velvety consistency.

Step 5: Chill and Let Flavors Meld

Transfer the sauce to an airtight container and refrigerate for at least 30 minutes before using. This chilling time allows all the flavors to meld together and the sauce to thicken slightly.

I’ve found the flavors deepen after 2-3 hours in the fridge, but it’s still delicious right away. The sauce will keep for up to 5 days refrigerated, though it’s so good you’ll probably use it all much sooner.

Wine and Beer Pairings for This Recipe

Crisp White Wines

A chilled Sauvignon Blanc with its citrus notes and bright acidity cuts through the creaminess beautifully. I love New Zealand versions from Kim Crawford or Oyster Bay—they have that zesty lime character that refreshes your palate. 🍷

Light Beers

For beer lovers, a crisp Japanese lager like Sapporo or Asahi pairs perfectly. The clean, slightly sweet profile complements the sauce without overpowering it. Serve ice-cold in a frosted glass for the best experience.

Sparkling Options

A dry Prosecco from Italy adds effervescence that cleanses your palate between bites. I find LaMarca or Bisol offer consistent quality. The bubbles also enhance the sauce’s creamy texture.

Rosé Choices

Dry Provence rosé with its subtle berry notes and mineral finish works surprisingly well. Look for Whispering Angel or Miraval—their pale color and crisp acidity mirror the sauce’s elegance.

Chill it to 45-50°F for the best pairing experience. 💫

Non-Alcoholic Pairings

For a non-alcoholic option, try sparkling yuzu lemonade or green tea with lemon. The citrus and slight bitterness balance the sauce’s richness. I love Ito En unsweetened green tea for this purpose.
