Maestro placing last bits of crab apple on the new cooker (9)
I believe the answer is:
beethoven
'maestro' is the definition.
'placing last bits of crab apple on the new cooker' is the wordplay.
'placing' is an anagram indicator (I've seen 'placed' mean this (placing the letters)).
'last bits of' suggests the final letters.
'on' means one lot of letters go next to another.
'new cooker' becomes 'oven' (I've seen this before. I am not sure about the 'new' bit.).
The final letters of 'crab apple' are 'be'.
'be'+'the'='bethe'
'bethe' anagrammed gives 'beeth'.
'beeth'+'oven'='BEETHOVEN'
Can you help me to learn more?
(Other definitions for beethoven that I've seen before include "German barman" , "I composed" , "Composer of Fidelio, d. 1827" , "film" , "See 1" .)
