Bonfire toffee is also known as treacle toffee, Plot toffee, Tom trot, claggum, clak, or loshin du. It is popular on Bonfire Night and Halloween. The toffee has a unique taste resulting from the black treacle, also known as molasses. You'll never forget it!

  • 1 lb sugar preferably demerara
  • 4 1/3 floz water
  • 2 1/2 oz butter
  • 3 1/2 oz golden syrup substitute light corn syrup
  • 3 1/2 oz black treacle
  • 1 tablespoon white vinegar


  • Put all the ingredients into a strong saucepan and stir over a steady heat until the sugar has dissolved.
  • Bring to the boil and cook until the mixture reaches the 'hard crack' stage, 290 degrees F. Test the mixture; drop a teaspoon amount into a glass of moderately cold water--if it is done you will get a blob of toffee that is slightly stretchy but breaks with pressure (ie. not brittle). Too bendy or stretchy means it needs a little bit longer, so test again after a short time.
  • Pour into an oiled or buttered tin and either allow to set as a slab or mark in squared as toffee becomes partially set. Break when completely set.


Be careful not to allow the mixture long enough to burn as it will develop an unpleasant taste. The white vinegar aids against the formation of sugar crystals. 1/4 teaspoon of cream of tartar can also be used.
