Does any have any good tips for making alcoholic jello jigglers? I love to make jello shots and usually use cups, for Halloween I make them in syringes which people love. But I have tried jigglers twice now and they do not harden up enough to come out of their mold in a solid piece. The first time I just used the box recipe and made them in a pan, hoping to use cookie cutters to get them out. The second time I added a packet of unflavored gelatin to the mix and put them in ice cube trays sprayed with Pam... still didn't come out. Help???
