Pull the beef cubes from their pot and stir 3 cups of the braising liquid as well as the stock paste and honey into the pan of spiced veggies. Add the olives and raisins and bring to a simmer. Let cook 5 minutes, then add the beef, cilantro and half the lemon zest. Simmer 2 to 3 minutes to warm the meat through. Sprinkle the remaining lemon zest on top when serving.
