Particular recollection of cool drinks coming round (7)
I believe the answer is:
special
'particular' is the definition.
('special' can be a synonym of 'particular')
'recollection of cool drinks coming round' is the wordplay.
'recollection of' says the letters should be written in reverse (recollect letters in the opposite direction).
'cool' becomes 'ice' (icing is a kind of cooling).
'drinks' becomes 'laps' (lapping is a kind of drinking).
'coming round' indicates putting letters inside.
'ice' put within 'laps' is 'laiceps'.
'laiceps' back-to-front is 'SPECIAL'.
(Other definitions for special that I've seen before include "Exceptional or particular" , "Exceptional in intensity or quality" , "Designed for a purpose" , "Unusual, superior" , "Dish not on regular menu" .)
