I read a recipe that was for Caramel by using sweetened condensed milk in a can. They said to boil the can in a pot of water for 3hrs (UNopened can & label cut off), with the boiling water covering the can. & after cooling open the can & it'll be a brown color delicious caramel. Anyone ever heard of this? Would this be runny caramel like to drizzle over a cheesecake or would this be formable to put in a pan to cool & cut to make candy from?
