Antics involving salty ingredient (6)
I believe the answer is:
capers
'antics' is the definition.
('caper' can be a synonym of 'antic')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for capers that I've seen before include "Antics and pickled flower-buds" , "Jumps about to get flavouring buds" , "Jumps, runs about playfully" , "Skips, dances" , "Scrape over romps" .)
