From the Good Grips Collection. The OXO Good Grips two-cup/500ml Fat Separator easily separates fat for healthier gravies, soups and sauces. Equipped with a built-in strainer that catches unwanted bits, the fat rises to the top and only the cooking liquid pours out of the spout. Simply place the stopper in the spout to keep fat out while you pour. The integrated measurement markings make following recipes simple, and the splatter shield helps prevent splashing while you pour.
