Fans of fiery eats can now test their intestinal fortitude — in more ways than one — with Carolina Reaper pepper-tinged tacos recently introduced at Texas’ 600 DQ locations. The Minnesota-based chain best known for its frosty Blizzards launched the incendiary new menu item this week. Each butt-busting taco starts with a crispy corn shell filled with Carolina Reaper-infused Monterey Jack cheese, ground beef, lettuce and tomatoes and topped with a cilantro-lime crema.
