Evaporated milk is made by heating milk to remove about 60% of its water content, resulting in a creamier and more concentrated milk. On the other hand, sweetened condensed milk is made by combining evaporated milk with a ton of sugar and then heating it until the sugar is fully dissolved. It's like the difference between a plain cookie and a chocolate chip cookie - both are delicious, but one is definitely sweeter!
So, if you try to substitute evaporated milk for sweetened condensed milk, you'll likely end up with a dish that's missing that rich, sweet flavor. It's like trying to make a burger without the beef - it just won't be the same!
