A retail lout sent out for some food (11)
I believe the answer is:
ratatouille
'some food' is the definition.
The definition suggests a singular noun which matches the answer.
'a retail lout sent out' is the wordplay.
'sent' indicates an anagram (send can mean to excite or stimulate).
'out' means one lot of letters goes inside another.
'retail'+'lout'='retaillout'
'retaillout' anagrammed gives 'rattouille'.
'a' put into 'rattouille' is 'RATATOUILLE'.
'for' is the link.
Can you help me to learn more?
(Other definitions for ratatouille that I've seen before include "cooked vegetables in a dish" , "Film" , "Vegetable stew" , "Stewed vegetable dish" , "vegetable casserole" .)
