According to Global Post, if ribs are boiled, the meat should be simmered for approximately 45 minutes on medium-low heat. However, spareribs do not have to be boiled as a preparation for grilling or barbecuing the meat. Global Post explains that while boiling reduces grill time and increases the tenderness of the meat, much of ribs' flavors are lost during the boiling process.
When ribs are boiled, it only takes approximately 15 minutes to grill the meat on each side. That stands in stark contrast to ribs that are not boiled, as grilling without boiling takes approximately two hours over medium heat before the meat is tender enough to eat.
As an alternative to boiling, Global Post recommends roasting the ribs instead. The site states that roasting, unlike boiling, does not result in flavor loss. To roast the meat, place the ribs on a cookie sheet and cover them with foil. Bake the ribs in the oven at 350 degrees Fahrenheit for 90 minutes or until the ribs become tender. Follow by caramelizing and grilling the meat on the grill for 10 minutes on each side. Not only does this pare down the grilling time, the meat tastes better as well.
