Drink freshly made - and from bananas - containing energy (4)
I believe the answer is:
mead
'drink' is the definition.
(mead is a kind of drink)
'bananas containing energy' is the wordplay.
'bananas' becomes 'mad' (slang for insane).
'containing' is an insertion indicator.
'energy' becomes 'e' (physics symbol as in E=mc2).
'mad' going around 'e' is 'MEAD'.
'freshly made and from' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
(Other definitions for mead that I've seen before include "Old honey-based drink for dame" , "Honey-based alcoholic drink" , "The poetic field" , "Male shop worker" , "Alcoholic drink of fermented honey and water of old" .)
