Rice dish gives us hiccups to some extent (5)
I believe the answer is:
sushi
'rice dish' is the definition.
(sushi is a type of rice dish)
'gives us hiccups to some extent' is the wordplay.
'to some extent' indicates the answer is hidden within the clue.
'SUSHI' can be found hidden inside 'gives us hiccups'.
(Other definitions for sushi that I've seen before include "Rice and raw fish wrapped in seaweed" , "fare from Japan" , "exotic dish" , "Exotic food" , "Japanese cuisine" .)
