Dish from poor area mostly in part of Iberia (not north) (9)
I believe the answer is:
spaghetti
'iberia not north' is the definition.
I can't tell whether this defines the answer.
'dish from poor area mostly in part' is the wordplay.
'dish from' becomes 'spa' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'poor area' becomes 'ghetto' (I've seen this before).
'mostly' means to remove the last letter.
'part' says to take the initial letters.
The first letter of 'in' is 'i'.
'ghetto' with its final letter taken away is 'ghett'.
'spa'+'ghett'+'i'='SPAGHETTI'
'of' is the link.
Can you help me to learn more?
(Other definitions for spaghetti that I've seen before include "Strings of pastas" , "Popular pasta dish, maybe bolognese" , "involving a fork and many turnings?" , "Pasta in long strips" , "Long thing pasta" .)
