Step #1 Disolve each packet of jelly crystals in one c of boiling water.
Step #2 Stand until room temperature.
Step #3 Add 1 c vodka to each jelly, then pour this into shot glasses & put in the fridge until set (about 3 hrs).
Step #4 * I actually used almost a c of vodka for each mix, but topped each up with a liqueur that complemented the jelly crystal flavour-limoncello for the lemon, grand marnier for the lime & cassis for the raspberry.
