- 3 envelopes (0.75 oz unflavored gelatin)
- ½ cup cold water
- 2 cups granulated sugar
- 1 cup light corn syrup
- 2 teaspoons pure vanilla extract
- 1 teaspoon peppermint extract
- ⅛ teaspoon salt
- Red food coloring
- ⅔ cup confectioners’ sugar (sifted, plus more for dusting)
- Grease an 9×13-inch pan very well, using a paper towel to rub it and make sure you fully coated the bottom, sides and edges of the pan. Set aside.
- In the bowl of a stand mixer fitted with the whisk attachment, combine the unflavored gelatin and 1/2 cup cold water. Let stand while you make the syrup.
- Place the sugar, corn syrup and ½ cup water in a medium saucepan and stir gently. Clip a candy thermometer onto the pan, and place it over medium-high heat. Bring it to a boil, checking it occasionally–you are looking for it to eventually hit a temperature of 235-240°F (soft ball stage).
- Once the syrup reaches 235-240°F, pull it from the heat. Carefully transfer the syrup to a large, heatproof measuring cup or a similar vessel with a spout for easy pouring. Turn the mixer up to medium speed and slowly pour the sugar syrup into the gelatin mixture. When all the syrup has been added, turn the speed to medium-high and let it go for about 10-12 minutes–the mixture should turn white and fluffy. Add the vanilla extract, peppermint extract, and salt and increase the speed to its highest setting for 1 more minute.
- Pour the marshmallow into the prepared pan and use an offset spatula spritzed with cooking spray to even it out. Working quickly, drop dots of red food coloring across surface of marshmallow. Using a toothpick, swirl food coloring into marshmallow to create a marble effect. Tap the pan on the counter a few time to get rid of air bubbles. Sift powdered sugar evenly and generously over the top. Let sit for about 6 hours or until firm.
- Use a knife to loosen the marshmallow from the edges of the pan and invert it onto a powdered sugar-dusted work surface. Dust the marshmallow slab with more confectioner’s sugar and cut into whatever size pieces you wish (a pizza cutter works great here). Dip the sticky edges of the marshmallows in more powdered sugar and shake in a sieve to remove excess powdered sugar. Store in an airtight container for up to 1 week.
