It’d be out of place in crab menu (5,3)

I believe the answer is:

cream bun

I'm a little stuck... Click here to teach me more about this clue!

'it'd' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'out of place in crab menu' is the wordplay.
'out of place in' is an anagram indicator.
'crab'+'menu'='crabmenu'
'crabmenu' with letters rearranged gives 'CREAM BUN'.

'be' acts as a link.

Can you help me to learn more?

(Other definitions for cream bun that I've seen before include "Teatime treat" , "Small rich cake" .)

I've seen this clue in The Times.
