Equipment

  • Mixing bowl
  • Whisk or spoon
  • Airtight container (for storage)

Ingredients
  

  • ½ cup mayonnaise
  • 2 tbsp ketchup
  • 1 tbsp yellow mustard
  • 1 tbsp pickle brine (or vinegar)
  • ½ tsp paprika
  • Dash of hot sauce (optional)
  • Salt and black pepper to taste

Instructions
 

  • Base: Add mayonnaise to a mixing bowl.
  • Blend: Whisk in ketchup and mustard until smooth.

  • Season: Add paprika, hot sauce, salt, and pepper.
  • Chill: Cover and refrigerate for at least 30 minutes to let flavors meld.

Notes

  • Taste after chilling—flavors deepen, so adjust seasoning before serving.
  • Consistency matters: Too thin? Add more mayo. Too thick? Add a splash of brine.
  • Variations: Try sriracha for spice, smoked paprika for depth, or fresh herbs for brightness.
  • Storage: Keeps well in the fridge for up to 5 days in an airtight container.
