ok it is simple........boil 8 oz water to dissolve jello, as normal instructions, then you add 8oz of COLD liquor of your choice, then you put into little plastic cups and put in fridge, it takes longer than normal to set up because of the alcohol, I think it took around 6 hours to set up.
I made one batch strawberry/everclear
another batch was lime/apple pucker
I read on the net somewhere that sugar-free jello works better with jello shots so that is what I used........worked perfectly
