Caramel In A Can - cooking recipe

Ingredients

1 (14 ounce) can sweetened condensed milk (any size I had to enter something here)
water

Preparation

Unopened can of sweetened condensed milk with the paper taken off.
Place the unopened can in a crock-pot. Completely submerge the unopened can in water.
Cook on the crock-pot's lowest setting for 8 hours. If using sous vide set it for about 200\u00b0F.
Cool down in the fridge for at least 2 hours. Cooling the can is the key.
Open and viola, you have caramel!
