Homemade Marshmallows – Recipe by Ina Garten

  1. In the bowl of a stand mixer fitted with the whisk attachment, add the gelatin and ½ C of cold water. Let sit while you make the syrup.
  2. Combine the sugar, corn syrup, salt, and ½ C water in a small saucepan over medium heat until the sugar dissolves. Raise the heat to high and cook until the syrup reaches 240° on a candy thermometer. Remove from heat.
  3. With the mixer on low speed, slowly pour the syrup into the gelatin. Put the mixer on high and whip until the mixture is very thick – about 15 minutes. Add vanilla and mix.
  4. Dust an 8X12 nonmetal dish with powdered sugar. (I used a 9X9 for extra tall marshmallows) Pour the marshmallow mixture into the pan, smooth out the top, and dust with more powdered sugar.
  5. Allow to stand uncovered overnight until it dries out.
  6. Turn the marshmallows out on to a board and cut into squares. Dust with more powdered sugar.
