ELI5: Why doesn't cold fat, such as lard, taste good to us like hot fat, such as bacon grease? Aren't they both high in calories and almost the same thing?

Your tongue doesn't taste that much. A lot of what we consider taste is actually from the nose smelling the food. Cold fat is less likely to give off the same amount of type of aromas as heated fat.

Also, comparing lard to bacon grease, the bacon grease has the added smell and taste of the cooked bacon in it, which gives it a very rich, meaty smell. Lard is generally pure fat, with no additional smells/tastes.
