heat oven to 180 C
whisk 4 eggs whites till frothy
whisk in 25o g caster sugar, till it goes silken, and you can make little peaks
fold in 1tsp of white wine vinegar and 2 tsp of cornflour and spread on a baking sheet covered in parchment paper.
turn oven down to 150C, and cook for 1 hour - 1 hour 15 minutes depending on your oven, it needs to be still quite pale. leave to cool in oven (that's why it needs to be slightly underdone)
heap piles of fruit and cream on once cool
and then forget to photograph it before it's all gone. - ok so that bit isn't part of the recipe - or the plan......
