(One 3-oz. box of prepared gelatin mixture makes about 15 serial killer mask gummies.)
Work in batches: Strawberry, Raspberry and then CherryIn a small saucepan, add 1 3-oz. box strawberry gelatin, 2 envelopes of unflavored gelatin, 1/4 tsp citric acid and 1/3 cup water. Whisk continuously over medium heat until the mixture is hot and all the gelatin is dissolved, about 2 minutes. Carefully pour strawberry gelatin into the Ghostface molds, working fairly quickly before the gelatin begins to firm up. Wash the saucepan and the whisk and repeat with remaining flavors.
Allow gelatin to set up at room temperature for about 30 minutes or refrigerate for 15 minutes and unmold the masked gummies. Enjoy!Store in an air tight container at room temperature for about a week.
