I took this recipe from a free leaflet the I picked up in Sainsburys some time ago and only got round to making it yesterday. I used a shops own brand Whiskey Cream Liqueur; but "Heather Cream" a Scottish liqueur or Baileys could be used; and it was great. Would go great with hot home made mince pies in the Christmas season. If you don't have an ice-cream maker pour the mixture into a freezer proof container, cover and place in freezer for 1 hour. Remove from the freezer and break up the mixture with a fork until it is "mousse" like to prevent ice crystals forming. Freeze again for a further hour and repeat the process, then freeze until solid. Remove from the freezer a few minutes before serving.
