Ingredients

4 cups ice (1 cup per person)

Plum syrup

500 gm plums (see note), pits removed, diced

200 gm caster sugar

1 tsp rosewater (or to taste)

Juice of 1 lime (or to taste)

Method

1.For plum syrup, combine ingredients and 200ml water in a saucepan and bring to the boil over medium-high heat. Stir, then continue to boil until plums start to break down (5-10 minutes). Remove pan from the heat and cool briefly, then blend with a hand-held blender to a purée and strain through a sieve (discard solids).

2.Process ice in a food processor until finely crushed. Spoon ice into chilled glasses and spoon over plum syrup. Top with extra ice, and serve.
