Found in cardamoms served up with bananas? (3)
I believe the answer is:
mad
'bananas?' is the definition.
(slang for insane)
'found in cardamoms served up' is the wordplay.
'found in' indicates a hidden word.
'served up' shows that the letters should be reversed in order.
'dam' is hidden in the letters of 'cardamoms'.
'dam' written backwards gives 'MAD'.
'with' acts as a link.
(Other definitions for mad that I've seen before include "Roused to anger" , "Insane - furious" , "Crazed" , "Idiotic" , "Extremely foolish" .)
