Take a mixing bowl and add mayonnaise. This is the creamy base of the sauce. Make sure it is smooth before adding other ingredients.

Add melted cheddar or cheese sauce into the bowl. Mix well until fully combined. This gives the sauce a rich and cheesy taste.

Add chili powder, paprika, garlic powder, onion powder and cayenne pepper. Stir slowly to mix evenly. These spices give the sauce its bold and spicy flavor.

Pour in your favorite hot sauce. Mix gently. This adds heat and tang. Adjust the amount based on your spice level preference.

Add vinegar or lemon juice. This step balances the richness. It adds a light tangy taste. Mix again until smooth.

Transfer the mixture to a small saucepan. Heat on low flame for a few minutes. Stir constantly. Do not boil. This helps blend all flavors together.

Taste the sauce and adjust salt or spice if needed. Add more hot sauce for extra heat or a little mayo to reduce spice.

Remove from heat and let it cool slightly. The sauce will thicken as it cools. Stir once before storing.

Pour the sauce into an airtight container. Keep it in the fridge. This helps maintain freshness and flavor.
