Notes

  • Use a candy thermometer for the most dependable results.
  • Don't stir once the mixture reaches a full boil.
  • Wipe sugar crystals from the sides of the pan with a damp pastry brush if needed.
  • Beat only until the mixture thickens and begins to lose its shine.
  • Store in an airtight container in the refrigerator for 2 weeks or freeze for 3 months.
  • Toasted pecans or walnuts make an excellent addition.
  • Let chilled fudge sit at room temperature for 10–15 minutes before serving for the creamiest texture.
