One advantage boiling has over straight grilling is cooking time. With a 45-minute to one-hour boil first, the spareribs will tenderize in the boil and need only go onto the grill to sear and caramelize on their exterior-- a process that only takes about 10 to 15 minutes, per side, over a medium-hot grill.
Once the water starts boiling, you should reduce the heat so that the ribs can simmer. Depending on the type of cut, ribs take around one hour to three hours to be cooked and tender. Thereafter, you can grill them but beware; it might not taste as nice as normally grilled ribs.
