The nice thing about the cheats no-churn ice cream is that you don't need a machine to make it. Better still, if you are completely out of time, you can simply use canned pears for this dessert for the ultimate in shortcuts. They won't have the gingerly flavours, but will provide more instant gratification. There is 15 minutes of actual cooking time involved, but the pears should rest in the poaching liquid for an hour before serving to cook through.
