Charred pineapple and cinnamon with habanero. It started as a summer seasonal for Tennessee Hot Sauce Co.'s subscribers, sold well enough that they made a second batch, and the subscribers voted it into the regular lineup.
The cinnamon is the surprise, and it's why this works on pork, shrimp and grilled chicken as well as tacos.
Heat: 5 out of 10.
Same heat but savory: Garlic Habanero. Milder: Poblano Jalapeño. Hotter: Smoked Ghost BBQ.
