Whisk for a further 5 minutes or until thick and glossy. Add cornflour and vinegar, whisking until combined.

Spoon 8 mounds of egg white mixture onto prepared trays, using back of a large spoon to make a slight indent in centre and create decorative peaks. Scatter with pistachios and rose petals then bake for 10 minutes. Reduce oven to 110°C and cook for a fur ther 1 hour. Turn off oven and allow meringues to cool completely, with oven door ajar.

Put thawed raspberries and icing sugar in a blender and puree until smooth. Strain through a fine sieve into a jug, discarding solids. Cover sauce and refrigerate.

Transfer meringues to a large serving platter. Put cream and vanilla in a large bowl and beat, using an electric hand mixer, until soft peaks form. Spoon a generous dollop of cream on top of each meringue. Put remaining in a serving bowl.
