1 teaspoon soy sauce
1/2 teaspoon wasabi (optional)

Ingredient Notes and Substitutions

Mayonnaise: The base of this recipe. You can use low-fat mayo for a lighter version.
Mentaiko: Adds a unique flavor. If unavailable, try using tobiko (fish roe) for a similar texture.
Lemon juice: Brightens the flavor. Lime juice works as a substitute.
Soy sauce: Provides umami depth. Tamari can be used for a gluten-free option.
Wasabi: Adds heat. You can skip it for a milder version.

How to Make Mentaiko Mayonnaise

Step 1: Gather Your Ingredients

Before you start, gather all your ingredients to ensure a smooth process. Having everything at hand makes cooking more enjoyable.

Step 2: Prepare the Mentaiko

Take the mentaiko and slice it open to remove the roe. This allows you to mix it evenly with the mayonnaise.

Step 3: Mix the Base

In a mixing bowl, add the mayonnaise. This is the creamy foundation that will carry all the flavors.

Step 4: Add Mentaiko

Add the prepared mentaiko to the bowl. Stir it in well to incorporate the flavors thoroughly.

Step 5: Add Lemon Juice

Pour in the lemon juice. This will brighten the mayo and balance the richness.

Step 6: Add Soy Sauce

Stir in the soy sauce for that umami flavor. This step is key to achieving the depth this mayo needs.

Step 7: Include Wasabi (Optional)

If you like a bit of heat, add the wasabi. It will elevate the flavor profile with a nice kick.

Step 8: Mix Until Smooth

Use a whisk or electric mixer to blend everything until smooth. You want a creamy, cohesive texture.

Pro Tip: For a smoother texture, use a food processor instead of whisking by hand.

Tips for the Best Mentaiko Mayonnaise

Use high-quality mayonnaise for the best flavor.
Adjust the amount of mentaiko based on your taste preference.
Let the mayo chill for at least 30 minutes before serving to enhance the flavors.

Common Mistakes to Avoid
