Put the cinnamon, ground cloves, nutmeg, apple juice and vanilla extract in a large saucepan. Bring to a gentle simmer.
When the apple juice has warmed through, add the vanilla ice cream and whisk vigorously with a balloon whisk until melted and combined with the hot apple juice – the ice cream should make a frothy top on the juice.
Pour a splash of dark rum into the bottom of the adults’ cups and top up with the hot punch. Garnish with Apple crisps (see 'Goes well with').
