Papa Murphy's Italian Vinaigrette
This vinaigrette runs high, mostly because of the aged parmesan blended into it.
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.
It is a blend of water, apple cider vinegar, sugar, parmesan cheese, and oils.
-
Aged parmesan — parmesan is a hard, aged cheese, and aging is what builds up histamine, so it pushes the whole dressing high.
-
Vinegar and oil — the apple cider vinegar and soybean oil each land on the moderate side, so even setting the cheese aside this is not a gentle dressing.
A plain oil drizzle on your salad is a much lower-histamine way to go.
