You won't find so much in pickles, sauces, etc. (4)
I believe the answer is:
less
'you won't find so much' is the definition.
I can't tell whether this definition defines the answer.
'in pickles sauces etc' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LESS' is hidden in the letters of 'pickles sauces etc'.
Can you help me to learn more?
(Other definitions for less that I've seen before include "more, as they say" , "In smaller quantity" , "Wanting" , "inferior" , "A smaller amount" .)
