Whisk the egg whites to a soft peak in the Kambrook bench mixer. Add the caster sugar, one tablespoon at a time, whisking well between additions.
Add the cornflour and vinegar and whisk for 5 minutes.
Put a little meringue between your thumb and pointer fingers and feel if there are any grains of sugar in the meringue. If there is, keep whisking until it is dissolved.
Once dissolved, divide the meringue between 4 bowls and add a tiny drop of red food colouring and a drop of strawberry essence to one bowl and stir through. Stir a tiny drop of pink food colouring and rosewater to one bowl. Stir through a drop of blue food colouring and vanilla essence to one bowl. Add a teaspoon of drinking chocolate powder to the last bowl and stir through.
Put one colour of meringue into a piping bag with a star tube in it. Pipe in a swirl, spacing the meringues 2cm apart. Repeat with all colours.
When piping is complete. Sprinkle a little extra of the drinking chocolate over the top of the chocolate meringues.
Turn the oven to 90°C and put the meringues in for 2 hours.
When complete, set the meringues in a dry area to cool completely. Place a handful of meringues in various colours into a cellophane bag and tie it up with ribbon for a perfect gift.
