Instructions

1. Bloom Gelatin

   Combine the gelatin with the cold water in a small bowl and let it sit until fully hydrated.

   Time: PT5M

2. Make Sugar Syrup

   In a saucepan, combine corn syrup, granulated sugar, and water. Attach a candy thermometer and heat over medium‑high until the temperature reaches 240°F (soft‑ball stage).

   Time: PT15M

   Temperature: 240°F

3. Melt Gelatin

   Set a heatproof bowl over a simmering pot of water (bain‑marie). Add the bloomed gelatin and stir until completely melted.

   Time: PT5M

4. Combine Gelatin with Syrup

   Slowly pour the melted gelatin into the hot sugar syrup while whisking continuously to incorporate air.

   Time: PT5M

5. Flavor Marshmallow Base

   Whisk in the unsweetened cocoa powder and vanilla extract until the mixture is smooth.

   Time: PT2M

6. Set Marshmallows

   Pour the marshmallow batter into a greased 9×13‑inch pan. Let it sit at room temperature until firm, about 30 minutes.

   Time: PT30M

7. Prepare White Chocolate

   Roughly chop the white chocolate and spread it in a single layer on a sheet pan lined with parchment paper.

   Time: PT5M

8. Bake White Chocolate to Amber

   Preheat the oven to 250°F. Bake the white chocolate for 10 minutes, stir, then bake another 10 minutes. Repeat the 10‑minute bake‑stir cycle until the chocolate turns a deep amber hue (about 30 minutes total).

   Time: PT30M

   Temperature: 250°F

9. Caramelize Sugar

   In a clean medium saucepan, melt 1 cup of granulated sugar over medium heat. Swirl the pan until the sugar turns a dark mahogany color.

   Time: PT10M

10. Add Cream and Milk

    Carefully whisk in the heavy cream, then the whole milk. Heat gently, stirring, until the mixture is smooth and glossy.

    Time: PT5M
