In a medium saucepan, combine the cranberries, granulated sugar, water, orange zest, and orange juice. Cook over medium heat, stirring occasionally until the cranberries burst and the mixture thickens, which should take about 10 minutes. Remove from the heat and carefully press the mixture through a fine mesh sieve to remove any skins. Stir in the vanilla extract and set the puree aside to cool slightly.

In a small bowl, sprinkle 1 teaspoon of gelatin over 2 tablespoons of cold water and let it bloom for about 5 minutes. Once bloomed, gently heat the gelatin until fully dissolved. Stir this mixture into the slightly warm cranberry puree and mix thoroughly. Allow it to cool to room temperature.

In a chilled mixing bowl, whip 3/4 cup of heavy cream until soft peaks form. Gently fold the cooled cranberry mixture into the whipped cream until you achieve a smooth and uniform consistency. If you're looking to enhance the color further, add a few drops of pink or red gel food coloring while being gentle to maintain the mousse texture.

Bloom additional gelatin: In another small bowl, combine 1 teaspoon of gelatin with 2 tablespoons of cold water. Allow it to bloom for 5 minutes, then gently heat until dissolved. In a separate chilled bowl, whip 1 cup of heavy cream with powdered sugar and vanilla bean paste (or extract) until soft peaks form. Stir in the dissolved gelatin until fully incorporated.

With the base of your mousse prepared, spoon or pipe the vanilla mousse into the bottom half of 6 to 8 small dessert glasses. Carefully layer the cranberry mousse on top, either with a spoon or a piping bag to ensure clean layers. Chill the assembled cups in the refrigerator for at least 2 hours, or until the mousse is fully set.

Just before serving, add a touch of elegance by topping each mousse cup with sugared cranberries and a fresh mint leaf. This whimsical garnish not only looks gorgeous but also adds a delightful crunch and freshness that complements the creamy mousse.
