Rose petal sorbet is an elegant, fragrant Mexican frozen treat with floral notes. This family-friendly, fresh dessert is a delicate, beautiful, traditional confection from Oaxaca.
Gently rinse the rose petals under cool water and pat dry to remove any dust or debris.
Combine water and sugar in a small saucepan and heat over medium, stirring constantly, until all sugar is dissolved and the syrup is clear; remove from heat and let cool to room temperature.
Blend the rose petals with lemon juice and rose water in a blender until very smooth, then strain the mixture through a fine mesh sieve to remove any solids.
Mix the cooled syrup thoroughly with the rose petal mixture in a large bowl, ensuring even integration. Taste and adjust with extra lemon juice if desired.
Pour the mix into an ice cream maker; churn according to the manufacturer's instructions (about 30–40 minutes) until light and frozen, then transfer to a container and freeze for at least 1 hour to set before serving.
