Whisky and Raisin Ice Cream

I have based this recipe on a Spanish ice cream flavoured with sweet sherry that I make at Christmas time, and to finish it off I have drawn from some of the simple ingredients that flavour the traditional Scottish cranachan – toasted oatmeal and raspberries. Both the sherry and whisky versions marry well with a dram but the cranachan version is like a scoop of Scotland in a bowl.
