Pinterest is great, amirite?! I found this nifty way to make caramel without any mess, or hassle. All you do is boil a can of sweetened condensed milk for 3 hours and BOOM, you have caramel. Make sure that the entire can is submerged in water while boiling. The great thing is you can make as many as your pot will handle!
FYI, let the can cool for at least 6 hours before opening.
