Simmer the beef ribs in the Cherry Coke and 1 or 2 onion quarters in a large pot over medium heat for about a half hour.
Meanwhile, prepare the marinade by warming the cherry juice in a large saucepan over medium-high heat.
Add salt, pepper, remaining onion quarters, cinnamon, orange, lemons and limes and about 1/2 liter of Cherry Coke. Heat the marinade until near to the boiling point.
Refrigerate to marinate the parboiled beef ribs for about 2 hours prior to grilling.
Grill slowly over a low flame or coals for about an hour until done, turning and basting with leftover marinade that has been reheated to boiling or with your choice of BBQ Sauce. The grilling time of 2 or 3 hours is greatly reduced because the beef ribs were partially cooked during the parboiling and marinating process.
