Preparation Method
Combine the Base: In a medium glass or stainless steel mixing bowl, whisk together the Mayonnaise and Ketchup until the color is uniform and pale orange.
Add Acids: Stir in the Lemon Juice and White Vinegar. The acidity will slightly thin the mayo, making it easier to incorporate the dry spices.
Incorporate Spices: Add the Paprika, Garlic Powder, and Dried Parsley. Whisk vigorously to ensure there are no clumps of garlic powder or paprika.
Heat it Up: Fold in the Sriracha and Tabasco. Taste at this stage; if you want a deeper smokiness, you can add an extra pinch of paprika.
The Chill Factor: Transfer the sauce to an airtight container. Refrigerate for at least 30 minutes before serving. This is crucial—it allows the dried parsley to soften and the flavors to meld.
