Crock Pot SCRBC909-PS Trio Cooker and Buffet Server. Traditional Buffet Warmers have flooded the marketplace for years. However the ability to actually cook food directly in the unit has not been available. With the launch of the Crock Pot Trio Cook and Serve, consumers can now create the entire entree / appetizer / etc in one pot, with a design they are proud to put on display. SCRBC909-PS contains three 3qt stoneware inserts for preparing several dishes at once. Three individual temperature controls allow the pots to cook food at a low, high or warm setting. Glass lids, a stainless and black hybrid finish and integrated handles offer a sophisticated look and practical style.
