Remove vegetables from oven and scrape them into a large saucepan. Add ketchup, cider vinegar, orange juice, brown sugar, white vinegar, Worcestershire, molasses, chili powder, paprika, coriander and cumin and whisk to combine. Bring to a boil over high heat. Reduce heat to low and simmer, uncovered, 2 hours or more, stirring occasionally, until liquid is thick enough to coat the back of a spoon. Let sauce cool to room temperature.
