FAQs
How hot is Lunacy sauce?
It uses Carolina Reaper peppers, but the pineapple and lime make the heat build slowly instead of hitting all at once.
Which subs pair best with Lunacy?
It pairs especially well with the Hook & Ladder and Jamaican Jerk Turkey, where the sweet fruit flavor balances salty meats.
Can I buy a bottle at Firehouse Subs?
Yes. Many locations sell bottles at the counter, often for less than buying online.
Does Lunacy sauce need refrigeration?
Yes. While it’s shelf-stable unopened, refrigerating after opening keeps the fresh fruit flavor.
Why does Lunacy sauce contain vanilla?
The vanilla smooths out the heat and acidity, giving the sauce a balanced, tropical glaze-like taste.
