Mix your two base ingredients together on a baking tray. If it is too difficult for you to mix them on the tray, just mix them on a bowl and then pour them onto a baking tray. Obviously, you will need a baking tray with a little depth to it to keep the liquid from pouring off.
If you are adding anything to the ice cream for flavoring (strawberries, chocolate, diced peaches, vanilla, etc.), then mix them in at this stage.
Place the baking tray into the freezer and let it freeze overnight or at least for five hours.
Take the tray out of the freezer and place it someplace flat. You may want to put it onto a kitchen mat or tea towel to keep it from moving as you roll out your ice cream.
Your ice cream is going to melt quickly, so you need to work quickly. Use an offset spatula and place it underneath the ice cream. Roll the ice cream in one straight line from one side of the tray to another, forming a spiral. Do the same thing again for all the ice cream until it is all in spiral rolls on the tray.
Use tongs to pick up the rolls of ice cream from the tray and place them in a bowl or cup.
