Is Culver's Culver's® Signature Sauce High in Histamine?

Culver's Culver's® Signature Sauce

High histamine

Culver's Signature Sauce is high because it packs aged cheeses, cultured buttermilk, and red wine vinegar.

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.

Dairy DAO Blocker Histamine Liberator

This is a creamy, tangy dip built on soybean oil, cultured buttermilk, and several cheeses with vinegar and spices.

Aged cheeses and cultured buttermilk — parmesan, romano, and blue cheese are all aged, and the buttermilk is cultured, which is exactly what pushes histamine high in dairy.
Red wine vinegar plus yeast extract and mustard flour — the red wine vinegar also acts as a DAO blocker, and the yeast extract and mustard flour add to the high reading.

A plainer dip made from fresh dairy would be much easier on this front.
