TIPS & ADVICE: The bottom seam is designed to let steam out of the roasting bag during cooking and is not leak proof, so it is best not to fill the bag with too much liquid. For best results, place foods in center of bag and avoid over-filling. After cooking, make a delicious gravy by simply adding liquid and corn starch to the juices at the bottom of the bag. Easily prepare a “one pot meal” by roasting vegetables, such as onions, potatoes or carrots, with meats. WARNING! Before cooking, do not lift roasting bag filled with ingredients as the bag can break. After cooking, use extreme caution when opening bag as the steam will be very hot.
