Papa Murphy's Pickles

High histamine

These pickles are high in histamine because pickling in vinegar and brine pushes cucumbers up.

This is sold raw and you bake it at home, which is the freshest case on this whole list. Nothing sits in a warmer, and you control how long it waits between the shop and the oven. Refrigerate it as soon as you get home and bake it the same day, because histamine builds up as protein foods sit whether that happens in a kitchen or in your fridge.

This is a simple topping of cucumbers cured in a vinegar-and-salt brine, and that curing is what drives the level.

  • Pickled cucumbers — the pickling process makes them high in histamine, since the cucumbers sit in brine and ferment rather than staying fresh.

  • Vinegar — the brine's distilled vinegar adds a moderate layer on top of the already-high pickles, so the whole topping lands high.

A fresh vegetable topping would sit far lower on the same pizza.
