The first recipe, perhaps, for track sport (7,3)
I believe the answer is:
formula one
'track sport' is the definition.
(sport that takes place on a track)
'the first recipe perhaps' is the wordplay.
'the first' says to put letters next to each other.
'recipe' becomes 'formula' (synonyms).
'perhaps' becomes 'one' (I can't explain this - if you can you should believe this answer much more).
'formula'+'one' is 'FORMULA ONE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for formula one that I've seen before include "Auto racing class" , "sort of GP" .)
