Mango and makrut lime bubble tea

1.For kaffir lime syrup, stir sugar and 250ml water in a saucepan over high heat until sugar dissolves, then stir occasionally until syrup reaches 121C on a sugar thermometer (8-10 minutes). Remove from heat, add lime juice and half the kaffir lime leaves and stir to combine.

2.Boil boba pearls in a large saucepan of water until they float to the surface (4-5 minutes), then reduce heat to very low, cover and cook until tender on the outside with a slightly firm centre (2-3 minutes). Drain and add boba pearls to kaffir lime syrup and refrigerate to cool.

3.Blend two-thirds of the mango with remaining kaffir lime leaves, lime juice and 3 cups of ice in a blender until smooth.

4.To serve, divide boba pearls and a little syrup among chilled serving glasses, top with mango smoothie and remaining mango pieces, then drizzle with remaining kaffir lime syrup. Serve straightaway and super-cold.
