if you want to buy one,Lakeland/qvc do Easi yo icecream mix which you ust add water to. It works out at 3 syns for 100ml but tastes like real ice cream. You don't have to buy their icecream maker just use a thick tuperware type container. Its really lush and 100ml is lots. Easy to do-add water and shake,freeze, allow to defrost slight,whisk with mixer and refreeze. One pack males 1.5 litres.Lakeland do smaller packs but qvc do it bulk which although cheaper is expensive to pay in one go unless someone shares the order.
