Whisk egg white in a stand mixer until super foamy and white.
Very gradually add the sugar a little at a time. When all the sugar is added, beat for another few minutes.
Either place large spoonfuls of meringue onto trays lined with baking paper, or pipe the meringue into ‘snowflakes’ by putting meringue mixture in a ziplock bag and cutting off one corner (best to watch the video for instructions here). If you’re going to use the snowflakes as decoration, place a small piece of drinking straw in the side of each meringue so you can later use this to make a hole for ribbon.
Bake for 30 minutes. Turn the oven off and leave for another 30 minutes.
