What is a Potato Bag? It is a fabric bag to "steam" some vegetables in the microwave.
This "potato bag" is "microwave friendly". Made of 100% cotton--even the thread is cotton--the potato bag can be used in the microwave to cook a variety of vegetables: potatoes, yams, squash; use your imagination. Like this: You put the potato in the bag and the whole works in the microwave. You don't want the edges to touch the sides of the microwave as it goes around. When your food is heated, lift it out of the microwave without burning your hand.
