From the internets:
This mold was one of my early recipe attempts and I did not write down the recipe… it was more of an experiment. But I can tell you that for any jello mold creation you want to use 25% less water than the package says for preparation to get a firmer mold. And you can replace some of the water in the preparation with other liquids. So in this case I used 3/4 cup boiling water to prepare a 3 oz package of lime jello. Stir for 2 minutes until all the granules are dissolved. Then stir in 1/2 cup cold tonic and a 1/2 cup cold vodka. If you want to suspend fruit in your mold, refrigerate the jello until it thickens to a gel and then stir in the fruit and spoon it into the mold. I used blueberries, but I think mandarin orange slices or sliced strawberries would be excellent. With fruit the yield will be about 2 cups. To make more, just double the quantities.
