How To make Meringues(Plain and Chocolate Filled)

4 egg whites
1 teaspoon pure vanilla extract
1 cup super fine sugar
Chocolate Ganache: 6 ounces bittersweet chocolate -- broken in pieces
1/2 cup scalded whipping cream
Preheat oven to 225 degrees. Have egg whites at about 70 degrees. Beat until foamy in an electric mixer or by hand. Add vanilla. While continuing to beat, add sugar one tablespoon at a time. When the mixture stands in stiff peaks on the beater, it is ready for baking. Fill a pastry bag with mixture and pipe onto parchment covered baking sheet, using star tip to create kisses. Bake about 1 hour or longer, depending on the size. Do not remove from the oven at once, but turn off the oven, open the door and leave them for at least 5 minutes. Cool gradually, away from a draft. Remove them from the sheet when cool. To prepare chocolate ganache, pour hot, scalded cream over chocolate. Blend until smooth. Cool.
To fill meringues, crush the bottom lightly with the thumb while still warm. Fill the hollows with chocolate ganache.
