2-3 envelopes plain gelatin (your call, but use 3 if the jelly shots will be sitting out for a while, at your birthday party)
2/3 cup white cake flavored vodka
Whipped cream and multi-colored sprinkles, for garnish, if desired
Prepare the silicone mold. Lightly spray mold with non stick cooking spray. Wipe off the excess spray with a paper towel. A slight residue should remain, just enough to help unmold the gelatin, without affecting the taste or appearance.
Pour the juices and cream into a saucepan and sprinkle with gelatin. Allow to soak for a few minutes. Heat on low, stirring constantly, until gelatin is fully dissolved (about 5 minutes). Remove from heat.
Stir in the vodka. Pour into the molds, and chill until set, several hours or overnight.
To serve, unmold the jelly shots. Pipe on whipped topping with a pastry bag. Refrigerate until serving time. Immediately before serving, top with the sprinkles.
Makes 30 jelly shots.
