Hand round recipe that’s original (5)
I believe the answer is:
first
'original' is the definition.
(associated in meaning)
'hand round recipe' is the wordplay.
'hand' becomes 'fist' (hand curled into a fist).
'round' is an insertion indicator.
'recipe' becomes 'r' (abbreviation).
'fist' going around 'r' is 'FIRST'.
'that's' is the link.
(Other definitions for first that I've seen before include "Cardinal" , "Original" , "Preceding all others" , "See 1" , "Preliminary" .)
