Place the stopper in the spout, pour pan drippings into the Fat Separator. The strainer filters even the tiniest bits and the fat will rise to the top. Remove the stopper and pour, the cooking liquid comes out first, leaving the fat behind. Measurement markings make following recipes simple, and the splatter shield prevents splashing while you pour. When you’re done, this Separator is dishwasher safe, and there’s on-board stopper storage, so the stopper doesn’t get lost.
