Cloer Profi Oublie/Knieper maker Extra Coating The Cloer Profi Oublie/Knieper maker Extra Coating is ideal for making knickers (also known as New Year rolls) or ice cream cones. These waffles are made from a thin batter, which is poured into the iron. The appliance is perfect to use during New Year's Eve to bake poppers, but also in summer to make your own ice cream cones. An advantage of this iron is the extra coating. This is because the extra coating is extra resistant to sugar, which means that the waffles come out of the appliance very easily once the sugar has caramelised.
