Preserve trimmings of homemade lamb stew (6)
I believe the answer is:
embalm
'preserve' is the definition.
(as in embalming a body)
'trimmings of homemade lamb stew' is the wordplay.
I cannot really understand how this works, but
an anagram of 'lamb' is 'mbal' which is located in the answer.
The remaining letters 'em' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for embalm that I've seen before include "Preserve from decay in death with chemicals" , "Prepare corpse for preservation (6)" , "Preserve body, mummify" , "Preserve corpse from decay" , "Prepare for burial" .)
