Group circling the globe to find frozen dessert (6)
I believe the answer is:
sorbet
'frozen dessert' is the definition.
(sorbet is a kind of frozen dessert)
'group circling the globe' is the wordplay.
'group' becomes 'set' (set is a kind of group).
'circling' means one lot of letters goes inside another (circling can mean going around or containing).
'the globe' becomes 'orb' ('orb' can be a synonym of 'globe').
'set' placed around 'orb' is 'SORBET'.
'to find' acts as a link.
(Other definitions for sorbet that I've seen before include "Sherbet, water-ice" , "A flavoured water-ice served between courses" , "Fruit water-ice" , "Possible course" , "Water ice dessert" .)
