Dish, very dry, needs dipping in port (7)
I believe the answer is:
risotto
'dish' is the definition.
(I know that risotto is a type of dish)
'very dry needs dipping in port' is the wordplay.
I cannot quite understand how this works, but
'very' could be 'so' (both can mean 'extremely') and 'so' is present in the answer.
'dry' could be 'tt' (abbreviation for teetotal) and 'tt' is present in the answer.
'port' could be 'rio' (Rio de Janeiro is a port) and 'rio' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for risotto that I've seen before include "Perhaps Italian" , "Italian food" , "Savoury rice dish" , "Rice/stock dish" , "Italian recipe" .)
