Miss Lambert's Toffee

We had a teacher at primary school who used to make this and sell it in the playground. It was so popular she drafted in the parents to help and the recipe was shared at special evening classes. This toffee is the stuff of legends!

8oz sugar
3oz butter
2 desertspoons treacle or syrup depending on how you wish the toffee to taste
1 desertspoon vinegar.
glass of ice cold water.

Melt the butter and syrup, add the sugar and dissolve very slowly. When no granules left bring to the boil. When boiling add vinegar. and continue to boil testing a few drops in the water regularly to test when ready. When It is ready it forms hard crunchy blobs in the water. Pour into lightly buttered small square tin and leave to set. Break into pieces
