Firehouse Subs Pepper Jack Cheese

Moderate histamine

Pepper jack cheese is moderate, driven by the jalapeno peppers folded into it.

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.

Histamine Liberator

It is a fresh-style cheese made from pasteurized milk and cheese culture with jalapeno peppers mixed in.

  • Jalapeno peppers — the peppers are the moderate driver here and are what nudge this cheese up from a plain fresh cheese.

  • The cheese base — because it is a young, culture-set cheese rather than an aged one, the dairy part itself stays gentle.

A plain fresh cheese without the peppers keeps things on the lower side.
