Pavlova tips:

• Have egg whites at room temperature. This gives a better volume when the whites are beaten.When beating egg whites to make a meringue, make sure the bowl is clean and grease free otherwise the egg whites will not beat to a good foam.
• Use a cake tin to mark the 20 centimetre circle on baking paper.
• Cooling the pavlova in the oven helps keep it dry and prevent cracking. Sudden changes in temperature cause the pavlova meringue to crack.
• Don't fret too much if the pavlova does crack. The cream will hide the cracks.
