Step-by-Step Instructions

Step 1: Build the base

In a mixing bowl, add the full-fat mayonnaise and whisk until smooth and glossy. This forms the structural backbone of the sauce.

Step 2: Incorporate fat and acidity

Slowly whisk in the melted butter, followed by apple cider vinegar. This balances richness with gentle tang.

Step 3: Layer flavour

Add tomato paste, garlic powder, smoked paprika, onion powder, salt, and white pepper. Whisk thoroughly to ensure even dispersion of spices.

Step 4: Adjust texture

Add cold water, one teaspoon at a time, whisking until the sauce reaches a pourable yet creamy consistency.

Step 5: Rest and refine

Cover and refrigerate for at least 30 minutes. Resting allows flavours to fully integrate and deepen.

FAQs

Can I make this sauce dairy-free?
Yes. Replace butter with additional avocado oil mayonnaise for a fully dairy-free version.

Why does my sauce taste too tangy?
Reduce the vinegar slightly and allow the sauce to rest longer; acidity mellows over time.

Is this suitable for meal prep?
Absolutely. Prepare once and enjoy throughout the week for quick, flavourful keto meals.
