Manufactured without undue alarm being spread (9)
I believe the answer is:
marmalade
'being spread' is the definition.
(I've seen this before)
'manufactured without undue alarm' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'alarm' is 'armal' which is present in the answer.
'manufactured' could be 'made' (I've seen this before) and 'made' is located 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 preserve" , "Jame made from citrus fruits" , "Orange jam" , "Eleven's [PRESERVE]" , "confiture" .)
