Wharf Style Dungeness Cocktail

San Francisco's famous Fisherman's Wharf has many sidewalk seafood vendors along it's crowded streets; many have what are called "walk away" seafood cocktails. Small cups of either crab meat or shrimp with the classic horseradish-infused tomato sauce. I made a more modern version at a dinner the other night using shot glasses made from ice, rubber molds filled with water and frozen to make one ounce glasses (28.34G) The ice cold containers are great for keeping perishable foods cold and can be flavored with citrus juice for more flavor.
