Why use evaporated milk in fudge?
Evaporated milk is milk that has been cooked to reduce its water content. It is more stable than regular milk and it can be cooked at high temperatures without curdling, a real benefit to fudge. Unfortunately, there is no substitute for it in a fudge recipe. While you can use evaporated milk in place of regular milk in many circumstances, the same is not true in reverse. Also, be sure you do not confuse evaporated milk and sweetened condensed milk, as they are two entirely different products.
