Ingredients

Scale

Sauce Ingredients

  • 1 cup mayonnaise
  • 1/4 cup white vinegar
  • 1/4 cup honey (Adjust sweetness to preference)
  • 2 tablespoons Dijon mustard
  • 1 tablespoon sugar
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1/8 teaspoon cayenne pepper (Optional, for a slight kick)

Instructions

  1. Combine Base Ingredients: In a small saucepan, add the mayonnaise, white vinegar, honey, and Dijon mustard. This combination forms the creamy, tangy, and sweet foundation of the sauce.
  2. Warm and Whisk: Place the saucepan over low heat and whisk the mixture continuously until it becomes smooth and the ingredients fully combine. Do not cook; the goal is just to warm it slightly to help meld the flavors.
  3. Add Spices and Sweetener: Stir in the sugar, salt, black pepper, garlic powder, onion powder, and if desired, the cayenne pepper for a hint of spice. These seasonings create the signature flavor profile of the sauce.
  4. Blend Thoroughly: Keep whisking gently until all spices and sugar are evenly incorporated and the sauce has a uniform texture.
  5. Cool Down: Remove the saucepan from heat and let the sauce cool to room temperature to prevent condensation in storage.
  6. Store Properly: Transfer the cooled sweet onion sauce to an airtight container to preserve freshness and flavor in the refrigerator.
  7. Chill Before Serving: Allow the sauce to chill for at least 1 hour before use. This resting time lets the flavors fully meld, enhancing the overall taste experience.

Notes

  • Adjust the amount of honey to control the sweetness to your preference.
  • Cayenne pepper is optional and can be omitted if a milder sauce is preferred.
  • Store the sauce in the refrigerator for up to 1 week.
  • This sauce pairs well with sandwiches, burgers, salads, and as a dipping sauce.
  • Use a whisk for best blending results to achieve smooth consistency.
