2 1/2 lbs granulated sugar
1 can evaporated milk
1 tsp vanilla essence
Heat sugar, milk and butter in a large pot, slowly until sugar is dissolved.
Bring to a rolling boil, stirring all the time so it doesn't burn and stick to the bottom of pot, for 20-30 minutes.
Add vanilla and beat, I use hand held mixer, until it begins to set.
Pour into a greased baking tray.
Allow to cool for a little while and cut into pieces (it's easier when it's still fairly soft) let set.
