Small wooden dish (5)
I believe the answer is:
steak
'dish' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's a link between them I don't understand?
'small wooden' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'wooden' becomes 'teak' (teak is a type of wood).
's'+'teak'='STEAK'
Can you help me to learn more?
(Other definitions for steak that I've seen before include "Getting cut" , "Porterhouse, perhaps?" , "pale by the sound of it" , "High-quality cut of beef" , "High quality beef" .)
