Ingredients for a salad (3,8)
I believe the answer is:
raw material
This clue could be a double definition.
'ingredients for' is the first definition.
The definition suggests a singular noun which matches the answer.
'a salad' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
Can you help me to learn more?
(Other definitions for raw material that I've seen before include "something uncooked" , "Unprocessed resource" .)
