Infrequent choice (4)
I believe the answer is:
rare
This clue is a double definition.
'infrequent' is the first definition.
(similar in meaning)
'choice' is the second definition.
(I've seen this in another clue)
(Other definitions for rare that I've seen before include "difficult to find?" , "Rear up, being scarce" , "Very infrequent, lightly cooked" , "Not easily come by like undercooked meat" , "Scarce or uncommon" .)
