Looked angry when milk producer got in sleigh (7)
I believe the answer is:
scowled
'looked angry' is the definition.
I can't judge whether this defines the answer.
'milk producer got in sleigh' is the wordplay.
'milk producer' becomes 'cow' (I've seen this in another clue).
'got in' means one lot of letters goes inside another.
'sleigh' becomes 'sled' (synonyms).
'cow' inserted into 'sled' is 'SCOWLED'.
'when' is the link.
Can you help me to learn more?
(Other definitions for scowled that I've seen before include "Looked gloomy" , "Pulled a face" .)
