Question: what is the difference between green peppercorns and capers?
Answer: They are actually the unopened flower buds from the plant rather than a fruit like peppercorns. Capers are usually preserved in a salt brine or in vinegar, much like green peppercorns. ... However, capers are simply tangy or salty, they do not have the peppery flavor notes or mild heat that green peppercorns will provide.
