Culver's Peanut Butter Custard Base

Moderate histamine

This custard is moderate in histamine, from the peanut butter swirled in.

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 Dairy

It is Culver's frozen custard made with milk, cream, sugar and egg yolk, with peanut butter mixed in.

  • Peanut butter: peanuts are rated moderate and are often listed as a histamine liberator.

  • The custard: the fresh dairy, sugar and egg yolk are mild.

A small cup keeps it at the gentle end of moderate.
