Marshmallows
From Martha Stewart

2 1/2 tablespoons unflavored gelatin
1 1/2 cups granulated sugar
1 cup light corn syrup
1/4 teaspoon salt
2 tablespoons pure vanilla extract
Confectioners' sugar, for dusting

1. Combine gelatin and 1/2 cup cold water in the bowl of an electric mixer with whisk attachment. Let stand 30 minutes.
2. Combine granulated sugar, corn syrup, salt, and 1/2 cup water in a small heavy saucepan; place over low heat, and stir until sugar has dissolved. Wash down sides of pan with a wet pastry brush to dissolve sugar crystals.
3. Clip on a candy thermometer; raise heat to high. Cook syrup without stirring until it reaches 244° (firm-ball stage). Immediately remove pan from heat.
4. With mixer on low speed, slowly and carefully pour syrup into the softened gelatin. Increase speed to high; beat until mixture is very thick and white and has almost tripled in volume, about 15 minutes. Add vanilla; beat to incorporate.
5. Generously dust an 8-by-12-inch glass baking pan with confectioners’ sugar. Pour marshmallow mixture into pan.
6. Dust top with confectioners’ sugar; wet your hands, and pat it to smooth. Dust with confectioners’ sugar; let stand overnight, uncovered, to dry out.
7. Turn out onto a board; cut marshmallows into any shape you like, and dust with more confectioners' sugar.
