Marshmallows are a light, spongy confection made primarily with sugar and gelatin, although some recipes contain egg whites.
- About 1 cup (125 g / 4.4 oz) confectioners' sugar
- 3 ½ envelopes (2 tbsp plus 2 ½ tsp) unflavored powdered gelatin
- ½ cup (125 ml / 4.2 oz) cold water
- 2 cups (450 g / 16 oz) granulated sugar
- ½ cup (160 g / 5.6 oz) light corn syrup
- ½ cup (125 ml / 4.2 oz) hot water (about 115°F / 46.1°C)
- ¼ tsp salt
- 2 large egg whites
- 1 tsp vanilla extract
- ½ cup (125 ml / 4.2 fl oz) vegetable oil
- Oil the bottom and sides of a 13×9×2-inch (33×23×5.1-cm) rectangular metal baking pan, and dust the bottom and sides with some confectioners' sugar.
- In bowl of standing electric mixer or in a large bowl sprinkle gelatin over cold water and let stand to soften.
- In a 3 quart (2.8 L) heavy saucepan cook granulated sugar, corn syrup, hot water, and salt over low heat, stirring with a wooden spoon, until sugar is dissolved. Increase heat to moderate and boil mixture, without stirring, until a candy or digital thermometer registers 240 °F (116 °C), about 12 minutes. Remove pan from heat and pour sugar mixture over gelatin mixture, stirring until gelatin is dissolved.
- With standing or a hand-held electric mixer beat mixture on high speed until white, thick and nearly tripled in volume, about 6 minutes if using standing mixer or about 10 minutes if using hand-held mixer. In a large bowl with cleaned beaters beat whites (or reconstituted powdered whites) until they just hold stiff peaks. Beat whites and vanilla into sugar mixture until just combined. Pour mixture into baking pan and sift ¼ cup confectioners' sugar evenly over top. Cool marshmallow, uncovered, until firm, at least three hours, and up to 1 day.
- Run a thin knife around edges of pan and invert pan onto large cutting board. Lifting up 1 corner of inverted pan, with fingers loosen marshmallow and let drop onto cutting board. With a large knife trim edges of marshmallow and cut marshmallows into roughly 1-inch cubes. Sift remaining confectioners' sugar into a large bowl and add marshmallows in batches, tossing to evenly coat.
