Preheat oven to 100 degrees fan forced, and arrange rack into middle of oven
Line a large baking tray with baking paper (use a dab of oil under the paper to hold it into place)
Prepare your piping bag with the nozzle of choice and put aside ready to take the meringue when it is made (I use a size 11 nozzle, but use whatever size you like)
Place sugars into TM bowl and mill 10 seconds / speed 10, put aside into a separate container
Insert butterfly whisk
Add egg whites and cream of tartar to TM bowl and whisk 2 minutes / 60 / speed 3 / no MC
Add vanilla and set the Thermomix to whisk 2 minutes / 60 / speed 3 / no MC
In this first 2 minutes, start to immediately add the sugar a tablespoon at a time through the hole in lid
Open lid and scrape any sugar that has landed on the butterfly into the mix
Continue mixing for a further 5 minutes / 60 / speed 3 / no MC
Place meringue into piping bag, and remove any large air bubbles before piping … to do this I place the piping bag on its side on the bench, and use my hand or a scraper to push the mixture towards the nozzle … if there are large air pockets you will find it hard to get a nice even shape in your “bites” as you pipe out the meringue
Pipe mixture onto the baking tray allowing 3cm space between them for a slight expansion (as they are small you should get up to 30 onto a large tray, I pipe 6 across, and 5 rows down on a single tray)
Place tray into oven and bake for 3 hours … open the door and test a meringue … you should be able to lift it off the baking paper, if not close the door and bake a further 30 minutes if needed
Remove tray, and place meringues onto a cooling rack to come to room temperature (this won’t take long, about 20 to 30 minutes)
Once cool store in an airtight container where they will keep for at least four weeks
If desired, dust meringues in a little icing sugar … this helps to keep them “dry”, and also remove any chance of them becoming a little “sticky” if left out on a serving plate for too long in humid weather … but this is totally optional
