Start with a can of sweetened condensed milk. DO NOT OPEN it.
Peel the label off, submerse in water and boil for 3-4 hours. Keep adding water to ensure the can is always immersed. The longer you boil it the thicker your treat will be. I cooked this one for 4 hours and it was very thick.
Let the can cool till you can handle it. In hindsight a can that needs a can opener would have been easier to open the one with a key that you pull open.
Enjoy! With a spoon or in another recipe. I think it would be divine on French toast.
I was skeptical that this was going to work, and I have no idea how it works, but this is something that we will definitely try again!
