Homemade Marshmallow Sauce

Homemade marshmallow sauce can be used as a topper for ice cream or an ingredient.
To make Rocky Road, Phish Food, Marshmallow Fluff Ice Cream or S'mores Ice Cream, you would add this in the last 5 minutes of making the ice cream by folding it in.

Ingredients

  • 1 tsp gelatin, unflavored powdered
  • 1 cup water, ice cold
  • 1 1/2 cup sugar, granulated
  • 1 cup corn syrup, light
  • 1 tsp vanilla extract
  • 1 pinch salt, kosher

Instructions

  • Add the unflavored powdered gelatin to the mixing bowl of an electric mixer.
  • Add ice-cold water and stir to dissolve the gelatin, then set aside (adding hot water will activate the gelatin and make it rubbery and hard).
  • In a heavy pot over medium-high heat, add the sugar, corn syrup, and a pinch of salt.
  • Bring the sugar/syrup mixture to a boil, then keep it at a gentle boil until it reaches 240 degrees.
  • Start the mixer on low speed and add the hot sugar/syrup mixture. Increase speed and whip until white marshmallow sauce forms. This will take a few minutes on high.
  • Once the desired thickness of the sauce has been reached, add 100% pure vanilla and whisk briefly.
  • Serve right away or store in a jar (once cooled) with a lid in the fridge for up to a month. Use the marshmallow sauce wherever you would use store-bought, especially when making ice cream or ice cream parfaits.

Notes

I've used this Marshmallow Sauce mainly in homemade ice cream or on brownies.
