Ok before we get started, let’s first clear up some confusion around this Japanese spicy mayo.

What is the red sauce on sushi called?

That spicy red thing on sushi is usually spicy mayo or sriracha mayo. So basically mayo with some kind of hot sauce, usually sriracha due to its wide availability. Some restaurants also call it dynamite sauce because of the heat that it packs. And if you’d like to be able to control how much heat you want in your dynamite sauce, that’s why this recipe!

What is the spicy green paste with sushi?

This is called wasabi. It’s made from the grated root of the wasabi plant (a type of Japanese horseradish) and adds a pungent, spicy flavor to the sushi. It’s different from the spicy sriracha mayo/dynamite sauce we’re making, but both add heat to your sushi.

Ingredients / What Is Dynamite Sauce Made Of?

  • Mayonnaise: A creamy base that gives the sauce its rich texture. Get a store-bought one or DIY it using my 3-Minute Oil-Free Mayo recipe!
  • Sriracha: A spicy chili sauce that adds a fiery kick.

And if you’d like to make some homemade vegan fish roe, you would also need:

  • Couscous: Tiny pasta granules used to mimic the texture of masago. I know I know, this is unbelievable that we’re subbing fish roe with couscous, but trust me, it works!
  • Hot Water: Helps to cook and soften the couscous.
  • More Sriracha: Just a pinch to give that golden orange color to your masago!

Step-by-step Instructions

Make the Optional Masago: Mix sriracha and hot water, then add couscous. Cover and let it sit for about 5 minutes. Afterwards, fluff it using a fork.

They look so pretty and honestly, I still can’t believe that you could make homemade fish roe this easily!

Combine: In a small bowl, mix mayonnaise, sriracha, and the prepared masago (if using). You can also add the masago later on like I did here!

Serve: Transfer your dynamite sauce into a sauce bottle to drizzle, or use it as a dipping sauce for sushi, fries, or any of your favorite dish!

Top Tips

  • Boost the Heat: Add more sriracha if you want a spicier kick!
  • Simplify: This spicy mayo sushi sauce tastes amazing even without the masago, so feel free to skip it!
    • Plus, if your sauce bottle has a small opening, it’s best to leave out the masago because otherwise, the masago might get stuck.
  • Taste Test: The secret to any great home-cooked dish is that it’s tested by the person who’s gonna consume it!
    • Do a taste test and see if it’s missing some tang (in that case, then add a bit of lemon/lime juice), or if perhaps the sauce is too thick (in that case, then thin it out with a bit of water)!

Serving Suggestions

If you’re asking what to put spicy mayo on, I’ve got you!

Sushi, duh! – This spicy mayo pairs well with almost any sushi! From the humble Kappa Maki (Cucumber Roll), to Shiitake Roll, Kimchi Sushi, or Asparagus Sushi Roll. Yums!

Loaded Fries – If you haven’t tried my Korean Loaded Fries yet, this is the time. Crispy fries + caramelized kimchi + creamy dynamite sauce? Heaven on Earth!

Bowls and Salads – The best flavor enhancer! Pair with my Rainbow Poke Rice Bowl or any bowls you’re making to give them a flavor boost!

Does authentic sushi have mayo?

Traditionally, authentic Japanese sushi does not use mayonnaise. However, as time passed, some started using the Japanese Kewpie mayo. However, outside Japan, mayonnaise is a popular condiment for sushi. People have gotten creative with it, adding spicy mayo and even other sauces (like this Mango Sushi Sauce) to their sushi, making it more like a fusion food!

Storage and Meal Prep Instructions

Storage: Store in an airtight container in the refrigerator for up to a week.

Meal Prep: Any good meal prep needs a good sauce. And this spicy mayo is one of them. Double the recipe and refrigerate for up to a week. Use it to enhance various dishes throughout the week!

Freezing: Do NOT freeze since this will change the texture of the spicy mayo sauce.

It is mildly due to the sriracha sauce added to it. Sriracha is considered mildly spicy since its Scoville rating ranges from 1000 to 2200. Sriracha is definitely less spicy than Tabasco sauce.

Sriracha sauce is made primarily from chili peppers, vinegar, garlic, sugar, and salt, giving it a tangy, spicy flavor profile.

Regular mayonnaise is dairy-free, but it contains eggs. If you want a vegan version, be sure to check the labels or make your own at home using my Vegan Mayonnaise recipe using either silken tofu or cashews!
