To pop, it tastes sweeter (4)
I believe the answer is:
corn
This might be a double definition.
'to pop' is the first definition.
The definition and answer can be both related to consumption as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'it tastes sweeter' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for corn that I've seen before include "Get drunk commonly" , "Maize" , "Grain; hard skin" , "Something unoriginal - cereal plant" , "Cereal grass" .)
