You cant boil alcohol... it cooks it out... weak jello shots!

I put the bottles in the freezer for a while and use the ice cold alcohol instead of the cold water. Boil the sour mix instead of the alcohol. NEVER USE OJ IN JELLO SHOTS. It will not set up!

You can use OJ, add some extra Knox gelatin to the mixture for a true OJ flavor

I have been making this receipe for a long time, I do boil the alcohol. It does not ruin the alcohol, in fact, it brings out the flavor.

can jello shots be covered and placed in the freezer to set up?

What is "sweet and sour drink mix" ? Ive never heard of it!

YES, they can be put in freezer. When we have parties, I need to make so many that I run out of room in the fridge. They get almost slushy....yummy!

Arlene - Boiling the alcohol may bring out the flavor, but it removes the actual alcohol.
Rod B - Sweet and sour mix is sold at US supermarkets, etc. If you can't find it, you could probably get by with a simple syrup mixed with lemon and lime juice. Check the internet for a recipe.
Cheryl W - I think the problem with oranges is removed if you heat it up first. I haven't tested that theory yet though.
Thanks for the great recipe Crissi!
