The baking pans made for miniature cupcakes, with the paper liners, make excellent molds for gelatin shots (cocktail or mocktail version). The paper liners make it easy to form and serve the Jello shots, and they allow you to remove and handle the gelatin without having to touch the gelatin itself
Step 1: Version 1: Based on flavored sweetened gelatin mix.
I prefer my Jello shots to be a little bit more dense than a gelatin mixed for use as a dessert dish. This is particularly true if I'm including flavorings in addition to plain water. Mixing it with about 3/4 of the liquid seems to be a pretty good balance between having a more durable texture but not being chewy.
Flavored syrups, like the kind used in flavored coffee drinks and Italian soda, make for good flavor enhancers.
I mixed cherry flavored mix according to the box directions but replaced about half of the cold water with vanilla-flavored syrup.
Step 2: Starting with unflavored gelatin
I made gelatin shots with the same flavor as a Shirley Temple cocktail (the original mocktail!).
Instead of cold water, use ginger ale that has been stirred until the carbonation had outgassed. Then add a couple of tablespoons of grenadine syrup to taste.
