Preheat oven to 200F, line a large baking pan with parchment paper then trace 3-6" or 2-8" circles. Turn parchment paper so the pencil marks will be facing down.
In a bowl of a standing mixer, place the egg whites and sugar and mix with a hand whisk or a fork.
Place the bowl on top of a pan with simmering water (the water should not touch the bowl) and cook the egg mix while constantly stirring until the sugar has dissolved. About 3 minutes.
Remove from heat and mix mixture using the cage attachment for about 3 minutes on medium-high.
Stop mixer then add cornstarch and vanilla bean paste and keep mixing this time on high until a shiny, stiff pick is formed.
Spoon a 1/3 (or 1/2) of the meringue att eh center of each circle then use a spatula to gently spread the meringue within the lines of each circle.
Bake for 1h and 30 minutes.
Remove from oven and allow to completely cool.
