Raspberry Cosmo (Jell-O)

A make-ahead party-ready offering from "Hello, Jell-O!: 50+ Inventive Recipes for Gelatin Treats and Jiggly Sweets" by Victoria Belanger.

• Ready In: 3 hrs 5 mins
• Yields: 4 cups

Ingredients

• 2 (2 tablespoon) envelopes unflavored gelatin
• 1⁄2 cup cold water
• 1 1⁄4 cups cranberry juice
• 1⁄2 cup sugar
• 3⁄4 cup  cold triple sec (liqueur)
• 1⁄2 cup  cold vodka
• 2  tablespoons lime juice
• 1  cup fresh raspberry

Directions

1. In a large bowl, sprinkle the gelatin evenly over the cold water and allow the gelatin to absorb the water for 2 minutes.
2. In a saucepan, bring the cranberry juice and sugar just to a boil over medium heat.
3. Remove from the heat. Pour the boiling mixture into the gelatin and stir until the gelatin is fully dissolved.
4. Let the mixture cool; stir in the triple sec, vodka and lime juice. Refrigerate until thickened. (See Note 1 below.).
5. Fold in the raspberries. Spoon into a 4-cup mold or 5 to 8 martini glasses. Refrigerate until firm. (See Note 2 below.) Unmold and serve, or serve in the martini glasses.
6. Keep it in the refrigerator for a minimum of 3 hours for individual molds, at least 4 hours for 2- to 6-cup molds and at least 5 hours or overnight for 8- to 12-cup molds.
7. Note 1: The gelatin should be the consistency of an extremely dense pudding. Keep it in the refrigerator for approximately 1 hour and 30 minutes (depending on the volume, thickness and chilling temperature). This is best for when you will suspend fruit as you do in this recipe.
8. Note 2: The gelatin should not stick to your finger if you touch it. It should be immobile.
