While you're waiting, spread out the jello shot cups on a cookie sheet
Mix the Cranberry Jello crystals with 1 cup of the boiling water until the jello sugar has dissolved.
Add the fresh lime juice, cranberry juice, Vodka and Triple Sec (or Cointreau). Stir again.
Pour into jello cups.
Chill for 2 to 4 hours, or until jello has set.
Makes about 16 2-oz jello shots.
If you don't have Citron Vodka, you can substitute regular vodka
Putting the jello shot cups on the cookie sheet isn't absolutely necessary but it does make transporting the jello shots to the refrigerator. It also catches any spills. The red jello can stain your countertop.
Mixing the jello in a bowl with a spout or large measuring cup will make it easier to pour into the jello shot cups.
You may want to wait until the jello has cooled before putting the lids on the jello shot cups. That will prevent condensation from forming on the inside of the lid.
