Question
Use a clean cloth to wipe the front part of your tongue so that it is dry. Put some sugar or jaggery there. Could you taste anything? Why did this happen?

Solution
No, I could not taste a thing. It is because there was no saliva on the tongue. When the food mixes with saliva, then only we get its taste.
