Ingredients You’ll Need
Each ingredient in this sauce plays a crucial role in delivering its signature flavor. The foundation of the sauce is mayonnaise, which provides a smooth, creamy consistency that binds all the flavors together. Opting for full-fat varieties like Hellman’s or Kewpie ensures the best texture and taste. Dijon mustard introduces a subtle heat and tangy depth, perfectly complementing the richness of the mayonnaise. Ketchup adds a hint of sweetness and a rich tomato undertone that balances the acidity in the sauce. The secret ingredient, kosher dill pickle brine, enhances the overall taste with a punch of zest and brightness, preventing the sauce from feeling too heavy while imparting a slight pickled tang. A touch of cayenne pepper brings gentle warmth without overpowering the other flavors, allowing for spice adjustments based on preference. Finally, salt and black pepper play an essential role in fine-tuning the seasoning, ensuring every bite is well-balanced and flavorful.
Step-by-Step Instructions for the Perfect Sauce
Making this sauce is incredibly simple, but following the right steps ensures the best flavor and texture.
Step 1: Gather Ingredients
Before you begin, measure out all ingredients to make the mixing process smooth and hassle-free.
Step 2: Mix the Base
In a small bowl, whisk together the mayonnaise, Dijon mustard, and ketchup until smooth. This creates a well-balanced creamy foundation.
Step 3: Add Flavor Enhancers
Stir in the pickle brine and cayenne pepper, distributing them evenly throughout the mixture. These ingredients add complexity and a touch of spice.
Step 4: Adjust Seasoning
Taste the sauce and adjust by adding salt and black pepper as needed. Start with a small pinch and increase gradually to reach your desired taste.
Step 5: Chill for Best Results
Let the sauce sit for at least 10 minutes in the refrigerator before using. This allows the flavors to meld together, creating a deeper and more cohesive taste.

Recipe Tips
For extra tang, increase the pickle brine to achieve a sharper, more pronounced acidity. If you prefer more heat, add an extra pinch of cayenne or a dash of hot sauce for a spicier kick. To enhance the sweetness, a little more ketchup will bring in a richer, more balanced flavor. For a thicker consistency, opt for a high-quality, thick mayonnaise like Kewpie to create a denser texture. To deepen the flavors even further, prepare the sauce ahead of time and refrigerate it for several hours or overnight, allowing the ingredients to meld beautifully.
