I’m pretty sure the big majority of taste comes from our noses. If you pinch your nose, you won’t be able to really tell the difference between a potato and an apple. Moving it around in your mouth, similar to swooshing wine around while inhaling, brings the smell and flavor into the nasal passage.
Taste buds need saliva in order to recieve stimulus from the chemicals of food. Try to dry your tongue and taste anything, you won’t feel a thing.
