Be in a sort of cold confection (6)
I believe the answer is:
sorbet
'cold confection' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's a link between them I don't understand?
'be in a sort' is the wordplay.
'in' indicates putting letters inside.
'be' placed into 'sort' is 'SORBET'.
'of' is the link.
Can you help me to learn more?
(Other definitions for sorbet that I've seen before include "Water ice dessert" , "Mushy ice drink to cleanse the palate" , "Refresher course" , "Strobe (anag.)" , "Frozen dessert" .)
