1 honeydew melon, halved and seeds removed
1 cup milk
½ cup sugar
finely grated zest and juice of 1 lime
¼ cup combined basil and mint leaves
3 tablespoons caster sugar
Cut all the skin off the melon and roughly chop one half. Place in a food processor and process until smooth. Set the remaining melon half aside.
Put the milk and sugar in a small saucepan and bring to the boil, stirring to dissolve the sugar. Set aside to cool.
Combine the melon purée, milk and the lime zest and juice and pour into a freezer-proof container. Freeze until partially frozen then tip into a food processor and blend until smooth.
Pour the sherbet back into the container and place in the freezer.
Sugar: Put the herbs and sugar in a mortar and pestle and pound together to form a grainy paste.
To serve: Thinly slice the remaining melon and arrange on serving plates. Top with scoops of sherbet and scatter with the herb sugar. Serve immediately.
