A study found that ice cream tastes better when licked, verses using a spoon.
The reasoning for this, is said the taste buds on the tongue receive the flavor quicker, because the tongue warms the ice cream. When a spoon is used, it tends to keep the ice cream colder and the ice cream hits the roof of the mouth first and then quickly swallowed.
So don’t worry about getting messy when you are licking your favorite ice cream treat. You enjoy every lick!
