Set the oven to 90°C. Separate the egg whites one by one into a small bowl, then transfer each one to a larger bowl. Add the cream of tartar and salt to the bowl, then start mixing on low speed and gradually increase the speed to high.

Slowly add the sugar as the egg whites foam. This step has a big impact on the final meringue, so remember to take your time and really add the sugar. Once you''ve added the sugar, it''s time to whisk in the BAM vanilla paste. The meringue is ready when it has a thick "marshmallowy" texture and can hold a nice peak. If you are going to colour the meringue, we suggest adding a SMALL, small amount of colouring with a toothpick or skewer, then whisking with a whisk attachment to distribute the colour.

Stick the meringues on the baking tray, leaving at least a centimetre of space between them for air flow. Place on the centre rack to bake at 90 degrees for about 1 hour, then turn off the oven and leave it closed for another 1-2 hours. The meringue biscuits are ready when they are completely dry.
