I like pasta's recipe for presentation, but if you want a simple, workman's recipe for roast beef, try this:
1 cup cubed and peeled horseradish root, 1/2-inch pieces
3/4 cup vinegar
2 tsp. sugar
1/4 tsp. salt
Directions:
Combine all ingredients in a food processor or blender; process until pur�ed. Carefully remove cover of processor or blender, keeping face away from container. Cover and store in the refrigerator until needed. Caution; the longer it's stored the hotter it gets...
