Made an effort, but the best end got overcooked (6)
I believe the answer is:
strove
'made an effort' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for strove that I've seen before include "Made great efforts" , "Struggled" , "Endeavoured" , "Voters (anag) - made every effort" , "Tried hard for voters" .)
