'Brummie King' breaks shower dish (7)
I believe the answer is:
ramekin
'dish' is the definition.
(I've seen this before)
'brummie king breaks shower' is the wordplay.
'brummie' becomes 'me' (I can't explain this - if you can you should give a lot more credence to this answer).
'king' becomes 'k' (abbreviation for king in chess).
'breaks' means one lot of letters goes inside another.
'shower' becomes 'rain' (synonyms).
'me'+'k'='mek'
'mek' inserted into 'rain' is 'RAMEKIN'.
Can you help me to learn more?
(Other definitions for ramekin that I've seen before include "Small baking dish for one portion" , "Small fireproof dish used for baking and serving food" , "Baking dish for one person" , "Small fireproof bowl" , "pot" .)
