If it has a removable bowl, put that in the freezer- make sure that the freezer is on its coldest setting nd freeze overnight. Assemble the machinery and start it going BEFORE you pour in the ingrerdients. The ice cream is ready when it is thick, or if it starts thawing/melting around the edges- then scoop out and put it in a separate box in the freezer so it can harden completely. Allow the removable bowl to thaw completely before you wash it- do not put in the dishwasher!

Do you want a recipie for rum and raisin using sour cream?

100g Raisins
100mil dark rum
100g caster sugar
3 large egg yolks
350ml sour cream

Soak the raising overnight in the rum. Whisk the egg yolks and sugar together until fluffy. whisk in the soured cream and put into the ice cream maker. When the ice cream is nearly frozen add the raisins and the any rum that has not soaked in and continue to freeze in the ice cream maker, when frozen sufficiently, pour into a box and freeze in the normal way.

Ice cream makers are great, I used ours so much I wore it out :-(

It helps if you chill the ice cream mix down thoroughly before pouring into the machine. Usually takes about 20 mins of churning to thicken it up, ready for the freezer.
