This is easy and delicous, it is from The Frugal Gourmet Celebrates Christmas cookbook. This is great with prime rib, grilled steaks, grilled burgers, corned beef or anything, I've even used it on baked potatoes sprinkled with fresh chopped chive. If you need more or less, it's just equal parts of everything. Drain the horseradish on the side of the jar with a fork before you take it out to remove most of the liquid or the sauce will be watery.
