Passing mention of what served up in spaghetti Bolognese (4)
I believe the answer is:
obit
'passing mention' is the definition.
(I've seen this before)
'up in spaghetti bolognese' is the wordplay.
'up' is a reversal indicator (in down clue: letters go upwards).
'in' indicates the answer is hidden within the clue.
'tibo' is hidden in the letters of 'spaghetti bolognese'.
'tibo' written backwards gives 'OBIT'.
'of what served' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for obit that I've seen before include "late anniversary" , "Commemoration of a death (abbr)" , "Biography after death, in short" , "funeral service" , "19d to remember" .)
