Sponge Toffee

Sponge Toffee is an easy candy to make - one of the first I learned to make, as a kid - and it’s also one of the first recipes I blogged. Give it a try!

Equipment

  • 9 x 13 Baking Dish
  • Candy Thermometer

Ingredients

  • 2 ½ cups granulated sugar
  • ⅔ cup corn syrup
  • 6 tablespoon water
  • 2 tablespoon baking soda
  • 2 teaspoon vanilla

Instructions

  • Prepare a 9″ x 13″ cake pan with nonstick spray, or a light coating of vegetable oil or shortening. Set aside.
  • In a large saucepan, stir together sugar, corn syrup, and water. Attach a candy thermometer to the pan, making sure that it does not touch the bottom of the pan.
  • Bring mixture to a boil, and allow to cook until temperature reaches 300 degrees F (hard crack stage). From the time mixture starts boiling to the time it reaches 300F, do not stir.
  • Once mixture reaches 300F, remove from heat.
  • Add vanilla and baking soda, beating to incorporate. The mixture will start foaming quite a bit when you add the baking soda (chemical reaction!), so using a LONG wooden spoon is a good idea. The sugar will be very hot, and will burn if you get any on your hand as you stir. Be very careful and work FAST.
  • Dump foaming mixture into greased cake pan, spreading it out as evenly as possible. Allow it to cool completely.
  • Once toffee is cooled all the way through, remove from pan and snap into chunks / nuggets and serve.

Notes

  • Be sure to store toffee in an airtight container – the sugar will attract water from the air, and the toffee can go soggy.
 
  • While you definitely want the baking soda to be fully mixed in, know that how much you beat it affects the final texture.  If you beat it a lot, the air bubbles will be smaller than if you don't. 
 
  • If you like big, airy toffee, beat it the minimum possible, and GENTLY pour it into the pan. DO NOT disturb it - it will keep rising and developing big bubbles.
