This may be weird for those who grew up solely in the US.
When I was a kid in places like Bahamas, , Belize, and St. Thomas, people used it as a creamer in coffee or in certain dishes.
Sometimes, regular milk wasnt available so evaporated milk , being canned, was used as a substitute due to its high shelf life.
To clarify, this does not have the higher sugar content like condensed milk and is less viscous than that.
It has an off-white color compared to standard milk.
I use it as a creamer in coffee at home.
I also add it to scrambled eggs in addition to chili powder/pepper.
I never use it for cereal or as a straight up beverage though.
