Seafood starter to improve on urchin (6)
I believe the answer is:
scampi
'seafood' is the definition.
(type of seafood)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scampi that I've seen before include "Dish of cooked shrimps or prawns" , "Prawns, usually fried" , "Edible crustaceans" , "Fish dish, often in rings" , "Dish of crustaceans" .)
