Culver's Salted Caramel Custard Base

Low histamine

This salted caramel custard base is low in histamine, built on fresh dairy and eggs.

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 frozen custard base of milk, cream, egg yolk, sugar, caramel, and a little butter.

  • Fresh dairy and eggs — the milk, cream, and egg here are fresh rather than aged or fermented, so they keep the base low.

  • Caramel and sweeteners — the sugar, corn syrup, and natural flavors do not push the histamine up, so this stays an easygoing option.

On its own this is a solid lower-histamine pick, so the main thing is to skip high mix-ins like chocolate or nuts.
