Jam manufactured without undue alarm (9)
I believe the answer is:
marmalade
'jam' is the definition.
(I've seen this before)
'manufactured without undue alarm' is the wordplay.
I cannot really see how this works, but
an anagram of 'alarm' is 'armal' which is located in the answer.
'manufactured' could be 'made' (I've seen this before) and 'made' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for marmalade that I've seen before include "Orange jam" , "Eleven's [PRESERVE]" , "Jame made from citrus fruits" , "Spread" , "Breakfast preserve" .)
