In a medium-sized pot over medium heat, warm a good splash of olive oil. Lightly sauté the garlic and onions until translucent. When tender, add the brown sugar, molasses and honey. Bring to a boil to fully dissolve the brown sugar and allow them to lightly caramelize, then add the vinegar and cook for five minutes. Add ketchup and the spices. Lower the heat to medium low and continue simmering for 20 to 30 mins. Remove from heat and allow to cool.
