Cover and refrigerate for at least 30 minutes (for best flavor)
Garnish with a little fresh parsley and serve at room temperature
Notes
You can cut the oysters with a sharp knife, but you lose a little of the cottonseed oil in the process. I recommend using a bowl and a fork and just mash them until they're relatively smooth.Hummus - use a basic hummus; not a seasoned oneHorseradish - get a prepared horseradish that's usuallly in the seafood section of the grocery store. Do not use a "horseradish spread" or a "horseradish sauce" - you want the cold stuff.
