Tomato Ginger Gelée Clam Shooters

We decided to serve these shooters in small glasses, so in order for the gelée to slide out easily we made sure the tomato ginger water is thickened but not set. We call for 60 glasses in this recipe, but for simplicity the clams can be served in their shells: Double the amount of gelatin, keeping all other measurements the same, and chill the mixture with cilantro and clams in well-scrubbed shells instead. Whichever presentation you choose, it's very important to cook the ginger thoroughly and to clean the food processor because otherwise the enzymes from the raw ginger will inhibit the action of the gelatin.
