Rice dish makes us hiccup somewhat (5)
I believe the answer is:
sushi
'rice dish' is the definition.
(sushi is a type of rice dish)
'makes us hiccup somewhat' is the wordplay.
'somewhat' indicates a hidden word.
'SUSHI' is hidden in the letters of 'makes us hiccup'.
(Other definitions for sushi that I've seen before include "Asian food" , "Rice and raw fish wrapped in seaweed" , "rice dishes" , "Cold rice dish, often with raw fish" , "Exotic food" .)
