Bumpkin swallowed mince tart, making three in a row (3,5)
I believe the answer is:
hat trick
'three in a row' is the definition.
The definition suggests a singular noun which matches the answer.
'bumpkin swallowed mince tart' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'tart' is 'attr' which is present in the answer.
'bumpkin' could be 'hick' (synonyms) and 'hick' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'making' is the link.
Can you help me to learn more?
(Other definitions for hat trick that I've seen before include "Three consecutive wins" , "Taking three wickets with consecutive balls" , "Three-goal feat" , "Sporting set of three" , "Producing rabbits" .)
