Cookbook:Parboiling

Parboiling is the act of partly cooking an ingredient by boiling for less than the full time needed to cook it. For example, potatoes and other vegetables may be parboiled before being roasted (as in roast potatoes), or green beans may be parboiled (and immediately chilled in cold water) as a preparation for freezing.

This technique is also used as a method to quickly cook pork ribs before grilling, although I would never, ever, in my life, do this. You get pork broth if you boil ribs!
