In a small saucepan, heat together 1⁄4 cup water, raspberries, and hibiscus over medium-high heat until raspberries soften and liquid is red. Remove from heat and strain through a fine-mesh sieve into a heatproof bowl, discarding solids. Let cool completely.
Sprinkle gelatin over cooled raspberry mixture and let bloom for 5 minutes. Cook mixture over medium-low heat, stirring constantly, until gelatin dissolves. Remove from heat. Stir in rose water. Let cool slightly but use before jelly sets.
Notes
*We used Badia® Hibiscus Tea/Sorrel.
