Ingredients in Instant Egg-Free Kewpie Mayo

(Note: the full ingredients list, including measurements, is provided in the recipe card directly below.)

Aquafaba: The magic ingredient! This chickpea liquid emulsifies the oil beautifully, creating that smooth, creamy texture typical of mayo.

Rice Wine Vinegar: Adds a gentle tang that balances the richness and brings that subtle brightness Kewpie is known for.

White Miso Paste: Infuses the mayo with umami depth, giving it that savory, slightly nutty note that makes it irresistible.

Dijon Mustard: Provides a mild bite that helps with emulsification and flavor balance.

Salt & MSG: Essential for enhancing flavor and creating that iconic Kewpie umami punch.

Neutral Oil: Avocado, canola, or sunflower oil works best. Avoid olive oil—it can overpower the delicate flavor of the mayo.

Instructions

Let’s make this silky, dreamy mayo:

Combine Ingredients: In a medium bowl, whisk together aquafaba, rice wine vinegar, miso paste, Dijon mustard, salt, and MSG until fully blended.

Add Oil Slowly: While continuously whisking or running your blender, slowly drizzle in the neutral oil. Continue until the mixture thickens into a smooth, creamy mayo.

Adjust Flavor: Taste and adjust seasoning as needed. If you prefer a tangier mayo, add a little extra rice wine vinegar.

Store and Use: Transfer the mayo to an airtight jar or container. Store in the refrigerator for up to a week.

Serve and Enjoy: Use this mayo as a dip, sandwich spread, or drizzled over your favorite roasted vegetables, grain bowls, or sushi rolls.

Additional Tips

• Blend at high speed for a few seconds for ultra-smooth texture if using a hand blender.
