Pre heat oven to 110°C / 215°F .
Lightly grease a large oven tray then line with baking paper and then lightly grease the baking paper and then dust the tray with cornflour , shaking off the excess flour . Set aside till needed .
Place the egg whites into a clean dry bowl .
Using electric mixers , beat the egg whites till soft peaks form .
Gradually add the caster sugar , a little at a time (about a tablespoon full at a time) till mixture becomes smooth and glossy and that all sugar has been dissolved into the mixture . Then add the vinegar and mix will to combine .
Either spoon the prepared mixture onto the prepared lined tray or pipe the mixture onto the prepared lined tray , the choice is yours .
Place the tray of prepared Maringues into the preheated oven for at least 1 hour or until turned pale colour slightly and are firm and crisp . Now turn the oven off and leave the oven door open ajar slightly till they cool completely .
