- 0.5 cup Water (cold water for blooming gelatin)
- 2 packets Gelatin (about 14 g total, unflavored)

Instructions
Prepare the Pan
Brush the 8×8‑inch dish with a thin layer of vegetable oil, then dust it generously with powdered sugar, turning the dish to coat all sides.
Time: PT5M
Bloom the Gelatin
In the stand mixer bowl, pour ½ cup cold water and sprinkle the two gelatin packets over it. Let sit for a few minutes until fully hydrated.
Time: PT5M
Make the Sugar Syrup
Combine ½ cup water, 1½ cups granulated sugar, and 1 cup light corn syrup in a small saucepan. Stir over medium heat until the sugar dissolves, then continue heating without stirring until the mixture reaches 240°F (115°C).
Time: PT12M
Temperature: 240°F
Combine Gelatin and Syrup
With the mixer on low, slowly pour the hot syrup into the gelatin mixture. Increase speed to high and beat for about 5 minutes until the mixture becomes thick, glossy, and leaves a soft trail when the whisk is lifted.
Time: PT5M
Flavor and Season
Add 2 teaspoons vanilla extract and ¼ teaspoon salt to the marshmallow mixture and mix for 1 minute.

Using a spatula, pour the fluffy mixture into the dusted pan. Smooth the top with the spatula or clean, damp hands.
