What you need is: one pound of sugar. five table spoons of water. one table spoon of vinegar. three table spoons of treacle. eight ounces of butter. First put all the ingredience Except the butter into a deep pan and melt, when it is nearly boiling add the butter and stir gently. Go and fetch ice cubes from the freezer, put them in a jug or basin of cold water. now get the toffee tin greeced, I used a pie tin as it felt the right size, about 8 by 8 inches. Thoroughly greece it with the butter wrapper. The toffee should boil slowly for almost five minutes, drop a very small bit of the mix into the cold water, when you fish it out it will be all in a spidery shape when its ready and crisp, not tacky. When your happy with it, pour it slowly and gently into the tin, do not spill it, leave it to cool, I put mine into the switched off oven where it was safe. When the toffee is cool but still warm make tracks in it with a knife, this will help you smash it up more easily when its completely cold. I use a toffee hammer and its great fun smashing it up! Store it in an air tight plastic container and store in the fridge, it may stick together slightly when you get it out of the fridge to eat, just tap the tub on the table and it will loosen nicely. Enjoy
