Shaved ice with cherries, gin and lime

1.For cherry, gin and lime syrup, stir sugar, cherries, vanilla and 300ml water in a saucepan over medium-high heat until sugar dissolves, then bring to a simmer and simmer until cherries soften and liquid reduces to a syrup (12-15 minutes). Strain through a fine sieve, stir in lime juice and gin and refrigerate until chilled completely. Serve poured over shaved ice in chilled glasses, cups or bowls, with lime wedges and extra gin.
