Make your meringue by separating the egg whites from the egg yolks. Take extreme care to not get any yolk into the whites, even a tiny speck of yolk in the white will result in a failed meringue.
Whisk the egg whites until they are white and frothy with soft peaks. Slowly add the sugar until you have a glossy, opaque white mixture that is fully incorporated
Bake the mini meringue nests in the oven for 1 hour before turning the oven off and leaving until it has completely cooled. This allows the meringue nests to dry out
