In a large bowl, whip the heavy cream until it forms soft, billowy peaks.
Gently fold in the sweetened condensed milk along with the cherry blossom extract or sakura syrup, stirring just until the mixture becomes smooth and delicately fragrant.
Pour the mixture into a loaf pan or freezer-safe container, smooth the surface, and cover. Freeze for at least 6 hours, or ideally overnight, until perfectly set.
To serve, scoop into chilled bowls and finish with a light drizzle of cherry syrup. Garnish with edible flowers for a beautifully refined presentation.
