Inspired by Nigella's one step no-churn coffee ice cream, this treat is so easy to make and can be scooped and eaten straight from the freezer. The smokiness of the Laphroaig paired with the dark molasses sweetness of the caramel make this ice cream a seriously grown up delight! Don't be tempted to use a cheap blend in this recipe - it needs the depth of flavour that comes from a peaty Islay malt to make it work.
