Try swallowing story about dessert (6)
I believe the answer is:
gelato
'dessert' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'try swallowing story about' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'swallowing' is an insertion indicator.
'story' becomes 'tale' (synonyms).
'about' is a reversal indicator.
'tale' in reverse letter order is 'elat'.
'go' enclosing 'elat' is 'GELATO'.
Can you help me to learn more?
(Other definitions for gelato that I've seen before include "treat in Milan?" , "Italian-style ice cream" , "Italian ice cream" , "Frozen food" .)
