Made of heavy-gauge T304 stainless steel, this large stock pot dares you to try to fill it up. And best of all, you can steam cook with minimum water. Let food start to cook on medium heat, then, when the valve starts to whistle, push the lever until the word CLOSED appears. Turn the heat down to low and let the cooking process continue. This will help retain taste and valuable nutrients. This also eliminates the need for grease or oil in cooking. The deep steamer basket will hold a colorful bouquet of vegetables or fish for steaming. Handles are welded and riveted.
