I love meringue and even better, meringue cups that you can fill with whatever you like! For these, I filled them with chocolate ganache.
*2 eggs whites at room temperature
*1/2 cup of sugar
*1 tsp of vanilla extract
*1 pinch of cream of tartar
Beat eggs whites on low-medium until frothy.
Beat for about a minute then gradually add sugar.
Beat on high speed until glossy peaks form (about 5-7 minutes).
Using a star tip nozzle, go around in a small circle and pipe the base and the bottom.
Then pipe upwards making walls around the center.
Bake on 200F for about 1 1/2 hours. Let them sit in the over after you turn it off for about 30 minutes. Fill as you desire!
