Marshmallow
A marshmallow is a soft, spongy, and sweet confection typically made from sugar, water, and gelatin that is whipped to a light and fluffy consistency.
Ingredients
- 3 envelopes unflavored gelatin (about 21g total)
- 1 cup cold water, divided
- 1 ½ cups granulated sugar
- 1 cup light corn syrup
- ¼ teaspoon salt
- 1 tablespoon pure vanilla extract
- ½ cup powdered sugar (for dusting)
- ½ cup cornstarch (for dusting)
Instructions
Prepare The Pan
- Grease a 9x13 inch baking dish or line it with parchment paper.
- Mix powdered sugar and cornstarch together and dust the bottom and sides of the pan.
Bloom The Gelatin
- In the bowl of a stand mixer, pour in ½ cup of cold water.
- Sprinkle the gelatin over the water and let it sit for 10–15 minutes to bloom.
Cook The Sugar Syrup
- In a saucepan, combine the remaining ½ cup water, granulated sugar, corn syrup, and salt.
- Cook over medium heat, stirring until the sugar dissolves.
- Increase the heat to high and cook without stirring until the mixture reaches 240°F (115°C) on a candy thermometer.
Mix It All Together
- Carefully pour the hot syrup into the gelatin mixture while the mixer is running on low speed.
- Gradually increase to high speed and beat for 10–12 minutes, until thick and fluffy.
- Add vanilla extract in the last minute of mixing.
Pour And Set
- Quickly spread the marshmallow mixture into the prepared pan using a greased spatula.
- Dust the top with more of the powdered sugar-cornstarch mixture.
- Let it sit uncovered at room temperature for 4–6 hours or overnight.
Cut And Store
- Once set, remove from the pan and cut into squares using a greased knife or pizza cutter.
- Toss the marshmallow squares in the remaining dusting mixture to prevent sticking.
- Store in an airtight container for up to 2 weeks.
