Capers
Capers are high in histamine primarily because they're almost always sold brined or pickled, which allows histamine to accumulate.
The preservation method is the main issue with capers — nearly all commercially available capers have been fermented in brine.
-
Pickling process — the salt-curing and fermentation used to preserve capers allows bacteria to convert amino acids into histamine over time
-
Hard to find fresh — fresh capers before brining are low in histamine (and actually contain quercetin, a natural antihistamine), but the brined version is by far the most common
If a recipe calls for capers, using a small amount and rinsing them well may help reduce the histamine load slightly.
