In a large pan add sugar, syrup and vinegar, stir until sugar has dissolved, then reduce heat and do not stir any more. After about 7 to 10 minutes drop a little of the mix into a glass of cold water; if a brittle strand or bead is formed, it is ready.
Take off heat and add the bicarbonate of soda, mixing thoroughly. Empty into a greased dish or bowl.
Leave to completely cool down, then crack into pieces.
I was really looking forward to eating some old fashioned honeycomb but I followed the recipe to the letter and it went black and my kitchen was full of steam with the acrid smell of vinegar which made my eyes water lol, I think I should have judged the timing myself, thank you for the recipe I will try it again sometime - 19 Jul 2013
