6/8/23: Made this recipe to top smore pies, with the following modifications:

  • divided recipe by 2/3 to make slightly less marshmallow
  • used clear candi syrup instead of corn syrup

The result was fine but a little too tough.

For next time:

  • Just make candi syrup (2 cups sugar, 1/2 cup water, 1/8 tsp. cream of tartar) and don’t heat above 220°F.
