4 egg whites
a pinch of cream of tartar
220g caster sugar
Preheat your oven to 140℃ and line a large baking sheet with baking paper.
Add the egg whites to a clean large mixing bowl.
Sprinkle the cream of tartar over and start beating the whites with electric beater on medium speed.
Once you have a soft peak you can start adding a teaspoonful of sugar to the whites, while beating continuously.
Incorporate the sugar before adding another teaspoonful of sugar. (If you want to be technical, you should have 30 second intervals in between adding, whisking and more sugar!)
Beat the mixture until all the sugar is incorporated and it is stiff and glossy.
Add a few drops of food colouring and gently fold through.
Scoop the meringue into a piping bag and pipe 2cm diameter circles onto the prepared baking sheet.
Bake in the oven for 1 hour 15 minutes.
Switch off the oven but do not open it. Stand the meringues in the oven for 30 minutes.
Remove and cool completely.
Store in an airtight container at room temperature.
