Boil Condensed Milk to make Caramel

How bout a Magic Trick? - Put a sealed can of Condensed Milk (sweetened) in boiling water for 2 1/2 hours.... and when you open it... It will be Toffee!!

Seriously, so much easier than the "Stir, bubble, scrape, stir, freeze, etc..." method. However, make sure the can is COMPLETELY submerged at all times... otherwise it's not as magical lol
