This is a simple mayonnaise based sauce. The ingredients can be adjusted to taste.

Heather’s recipe tips

• I recommend letting the sauce sit in the refrigerator for at least an hour to let the flavors come together.
• If you would like a thicker sauce, add about 1/4 cup extra of mayonnaise.
• Horseradish is spicy. If you prefer a sauce that is less spicy, you can reduce the amount of horseradish.
