Heading west, sailor’s leading series of races in Uruguay’s River Plate (7)
I believe the answer is:
risotto
'plate' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'heading west sailor's leading series of races in uruguay's river' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is found in the answer.
'races' could be 'tt' (Isle of Man Tourist Trophy races) and 'tt' is present in the answer.
'river' could be 'r' (abbreviation for river) and 'r' is located in the answer.
The remaining letters 'iso' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for risotto that I've seen before include "Savoury rice dish" , "dishy thing!" , "Italian dish cooked with broth" , "It has roots in Italian rice-based dish" , "Italian course" .)
