Is Culver's Ken's® Boom Boom Sauce High in Histamine?

Culver's Ken's® Boom Boom Sauce

High histamine

Boom Boom Sauce is high in histamine, mainly from added sulfites and aged, spiced components.

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.

Histamine Liberator

This is a sweet-and-spicy sauce made from soybean oil, vinegar, sugar, egg yolk, aged cayenne, and several dried peppers and spices.

Sulfites and mustard oil lead it — the sodium metabisulfite and dried mustard oil are both high, and that alone sets the level.
Aged and moderate peppers add to it — the aged cayenne, red bell pepper, plum, rice vinegar, paprika, and soybean oil each sit at a moderate level, so the rest of the blend is not gentle either.

A plain, unsauced order or a simple oil-based dressing on the same menu is the lower-histamine path.
