Gather all your items on the kitchen counter. Measure each item before you start mixing. This makes the process very smooth and fast. Make sure your mayonnaise is at room temperature. Clean your workspace to stay organized and happy.

Put the mayonnaise into your large mixing bowl. Pour the apple cider vinegar over the mayo. Use your whisk to combine them slowly. Keep whisking until the mixture is very smooth. There should be no yellow lumps left now.

Squeeze the fresh lemon juice into the bowl. Add the prepared horseradish to the creamy mix. Whisk it again to distribute the spicy bits. The sauce will start to smell very tangy. It should look light and very inviting.

Sprinkle the salt and black pepper into the bowl. Add the sugar and cayenne pepper next. Use your whisk to blend the spices well. Make sure the sugar dissolves into the sauce. This creates a very balanced and deep flavor.

Take a small clean spoon for a taste. See if it needs more salt or spice. You can add more horseradish for extra zing. Make the sauce perfect for your own family. Trust your taste buds during this easy step.

Pour the sauce into your clean glass jar. Put the lid on the jar very tightly. Place it in the fridge for one hour. Chilling helps the flavors marry together well. Cold sauce tastes much better on hot meat.
