Spicy Mayo

Spicy mayo is one of those magical condiments that transforms everything it touches. This version goes beyond the standard sriracha-and-mayo combo by leaning into the deep, complex heat of fermented chili paste — think gochujang or homemade lacto-fermented hot sauce. The fermentation adds a subtle tang, umami depth, and a rounded heat that fresh chili simply cannot replicate. Whether you're drizzling it over a poke bowl, slathering it on a smash burger, or dunking crispy tempura into it, this spicy mayo will become a permanent fixture in your refrigerator.

Ingredients

• 1 cup (240g) high-quality Japanese mayonnaise (Kewpie strongly recommended)
• 3 tablespoons gochujang (Korean fermented chili paste)
• 1 tablespoon fermented sriracha or lacto-fermented hot sauce
• 1 teaspoon toasted sesame oil
• 1 teaspoon rice wine vinegar
• 1 teaspoon soy sauce or tamari (for gluten-free)
• ½ teaspoon garlic powder
• ½ teaspoon honey or maple syrup (to balance heat)
• 1 tablespoon fresh lime juice
• Pinch of fine sea salt, to taste

Instructions

Step 1: Gather and Measure

Measure out all ingredients before you begin. This recipe comes together in under five minutes, so having everything prepped and ready ensures a smooth process. Allow your mayonnaise and gochujang to come to room temperature for about 10 minutes if they have been refrigerated — this helps the ingredients blend together more smoothly and evenly.

Step 2: Combine and Whisk

In a medium mixing bowl, add the mayonnaise as your base. Spoon in the gochujang, fermented sriracha, toasted sesame oil, rice wine vinegar, soy sauce, garlic powder, and honey. Using a silicone spatula or small whisk, mix all ingredients together vigorously until the sauce is completely uniform in color and texture — a rich, deep coral-orange with no streaks of white remaining. This should take about 60 to 90 seconds of active stirring.

Step 3: Finish and Adjust

Add the fresh lime juice and stir once more to incorporate. Taste the spicy mayo and adjust seasoning as needed. Want more heat? Add another teaspoon of gochujang. Need more tang? A splash more rice wine vinegar. Prefer it slightly sweeter to tame the fire? Add a touch more honey. Season with a pinch of sea salt if the overall flavor needs lifting. Transfer to a squeeze bottle or an airtight jar and refrigerate for at least 15 minutes before serving to allow the flavors to meld and deepen.

Tips for Success

• Use Kewpie mayonnaise — its egg yolk richness and subtle tang make it far superior to standard American mayo for this application and produces a silkier, more cohesive sauce
• Don't skip the rest time — letting the finished spicy mayo chill for at least 15 minutes in the refrigerator dramatically improves the depth of flavor as the fermented components meld together
• Taste your gochujang first — fermented chili pastes vary widely in heat and sweetness by brand and age, so always taste before measuring and adjust accordingly
• A squeeze bottle is your best friend — transferring the finished mayo into a squeeze bottle gives you precise, restaurant-quality drizzling control for plating
• Balance is everything — the four pillars of this sauce are heat, fat, acid, and umami; if something tastes off, identify which pillar is missing and adjust that element

Variations

• Wasabi Fermented Mayo: Replace gochujang with 2 tablespoons of wasabi paste and 1 tablespoon of white miso for a Japanese-forward condiment with sharp, sinus-clearing heat — perfect for raw fish dishes
• Chipotle Fermented Mayo: Swap gochujang for 2 tablespoons of chipotle in adobo (blended smooth) plus 1 tablespoon of fermented jalapeño hot sauce for a smoky, Southwestern-inspired version ideal for tacos and grilled corn
• Miso Garlic Spicy Mayo: Add 1 tablespoon of white or yellow miso paste and double the garlic powder, then fold in 1 teaspoon of finely grated fresh ginger for an intensely savory, aromatic variation that pairs beautifully with roasted vegetables and grain bowls
• Extra Creamy Avocado Spicy Mayo: Blend the finished spicy mayo with half a ripe avocado until smooth for a richer, greener sauce with added healthy fats and a more subtle heat level — excellent as a dip or sandwich spread
• Vegan Spicy Mayo: Substitute your favorite plant-based mayo (such as Hellmann's Vegan or Just Mayo) for the Kewpie and use maple syrup in place of honey — the fermented chili paste carries the flavor beautifully regardless of the mayo base

Storage

Transfer your finished spicy mayo to a clean, airtight glass jar or squeeze bottle. It will keep refrigerated for up to 2 weeks. The flavor actually improves over the first 2 to 3 days as the fermented ingredients continue to meld. Always use a clean utensil when scooping to prevent contamination. Do not freeze spicy mayo — emulsified sauces break upon thawing, resulting in a greasy, separated texture that cannot be fully recovered. If the sauce appears to separate slightly after several days in the fridge, simply stir or shake vigorously to re-emulsify before use.
