Iced dessert in solidified state, round sphere (6)
I believe the answer is:
sorbet
'iced dessert' is the definition.
(I've seen this in another clue)
'solidified state round sphere' is the wordplay.
'solidified state' becomes 'set' (set is a kind of state. I am not sure about the 'solidified' bit.).
'round' is an insertion indicator.
'sphere' becomes 'orb' (orb is a kind of sphere).
'set' enclosing 'orb' is 'SORBET'.
'in' is the link.
Can you help me to learn more?
(Other definitions for sorbet that I've seen before include "Sherbet, water-ice" , "Frozen dessert" , "Strobe (anag.)" , "A flavoured water-ice served between courses" , "Flavoured water ice" .)
