Tasty thing MP dipped in salt pot (7)
I believe the answer is:
crumpet
'salt pot' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'tasty thing mp dipped in' is the wordplay.
'tasty thing' becomes 'cruet' (I can't explain this - if you can you should believe this answer much more).
'dipped in' is an insertion indicator.
'cruet' enclosing 'mp' is 'CRUMPET'.
Can you help me to learn more?
(Other definitions for crumpet that I've seen before include "Muffin" , "Light, soft yeast cake" , "Confection for toasting" , "Tea cake" , "Thick soft porous cake - attractive person" .)
