Is Firehouse Subs Chocolate Mint Cookie High in Histamine?

Firehouse Subs Chocolate Mint Cookie

High histamine

This chocolate mint cookie is high, driven by the chocolate chips and alkali-processed cocoa.

Food here is usually assembled to order from components that were prepped earlier in the day, so it tends to be fresher than a drive-through and less fresh than cooking at home. Histamine builds up as protein foods sit, so how long the chicken or beef has been in the warmer matters as much as what is in the bowl. Treat the rating above as a starting point.

A minty bake of wheat flour, mint chips, chocolate chips, cocoa, butter, eggs, and molasses.

Chocolate and cocoa lead it — both the chocolate chips and the cocoa processed with alkali are high in histamine, and they're central to this cookie.
The dough adds to it — the enriched wheat flour, margarine, and molasses are each moderate, so the base contributes even before the chocolate.

There's no lower-histamine way to order a chocolate-forward cookie like this.
