  • Prepare pan with parchment paper, securing with a little bit of shortening.

  • In a large pot, stir sugar, corn syrup, and water over medium heat. Bring to boil.

  • Cook, without stirring until a candy thermometer reaches 300 degrees F, about 10-12 minutes.

  • Remove from heat, and very carefully whisk in baking soda. The toffee will bubble up and rise very high in the pot.

  • Pour into prepared pan. Let cool in rack without disturbing, about 2 hours.

  • Using a meat tenderizer, mallet, or spoon, break toffee into nuggets.
