Ingredients:
- 170g unsalted European-style butter
- 45ml Kentucky bourbon
- 5g fine sea salt
- 565g fresh mini marshmallows
- 10ml pure vanilla extract
- 180g crispy rice cereal
- 1g flaky sea salt
Instructions:
- In a large heavy-bottomed pot, melt the butter over medium heat. Once melted, whisk in the bourbon.
- Continue cooking while whisking constantly. The mixture will foam and then subside. Look for mahogany-colored milk solids and a nutty aroma. Once deep amber, immediately reduce heat to low.
- Add 565g of marshmallows (minus a reserved 1 cup) and the fine sea salt. Stir continuously until approximately 90% melted.
- Remove the pot from heat and stir in the vanilla extract to stop the cooking process and prevent the sugars from hardening.
- Gently fold in the crispy rice cereal and the reserved 1 cup of marshmallows until evenly coated.
- Press the mixture into a parchment-lined 9x9 inch square baking pan. Sprinkle with flaky sea salt and allow to cool for 30 minutes before slicing into 16 squares.
