Is Culver's Tartar Sauce Cup High in Histamine?

Culver's Tartar Sauce Cup

High histamine

This tartar sauce is high, driven by green olives, capers, cured cucumber, and mustard.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

This is a mayonnaise-style sauce built from soybean oil and egg yolks, mixed with cured cucumber, green olives, capers, mustard, and vinegar.

Green olives, capers, and cured cucumber — these are all cured or pickled ingredients that are high in histamine, and any one of them is enough to make the whole sauce high.
Mustard bran and the oil — the mustard bran is also high, while the soybean oil and red bell pepper add a moderate layer underneath.

There is no clean tweak here, so a plainer low-histamine dip would serve you better.
