There are five levels of spiciness for the sandwiches at Jam Hot Chicken, a walkup window eatery in Winter Park’s Hannibal Square. The middle one is hot, which is what I ordered. I cannot imagine the fiery hell of the next level up, which is labeled hotter, let alone the spiciest one, jam. “You’ve been warned” is written next to that one on the menu. Woe to the person who mistakenly thinks jam means sweet jellied preserves.
