Iran is wrong - this is what you get when Shiraz is really dry? (6)
I believe the answer is:
raisin
'this is what you get when shiraz is really dry?' is the definition.
The definition suggests a singular noun which matches the answer.
'iran is wrong' is the wordplay.
'wrong' indicates anagramming the letters.
'iran'+'is'='iranis'
'iranis' is an anagram of 'RAISIN'.
Can you help me to learn more?
(Other definitions for raisin that I've seen before include "Large dried grape" , "Dried red grape" , "Dried grape used in cakes" , "Dried 18" , "A dried grape used in cake" .)
