Stock's quality about right for soup (10)
I believe the answer is:
minestrone
'soup' is the definition.
(minestrone is a kind of soup)
'stock's quality about right' is the wordplay.
'stock's' becomes 'mines' (I can't justify this - if you can you should believe this answer much more).
'quality' becomes 'tone' (synonyms).
'about' means one lot of letters goes inside another.
'right' becomes 'r' (common abbreviation).
'tone' going around 'r' is 'trone'.
'mines'+'trone'='MINESTRONE'
'for' is the link.
Can you help me to learn more?
(Other definitions for minestrone that I've seen before include "Item on menu" , "liquid mixture" , "A starter" , "Dish" , "F" .)
