Cookware Shop - Vacuum Pot

They come with two parts, namely the outer and inner pots.

Firstly bring soup ingredients and water to the boil over heat with the stainless steel inner pot. Then place the whole pot of soup into the outer pot instantly after removing heat and when the soup is still in the boiling state.

Lastly cover the lid of the outer pot. Since there is a layer between the outer and inner pots, it avoids the heat of the inner pot contact with the air outside the outer pot. This makes the soup at the boiling state without any fuel or electricity and saves energy. Vacuum pots are fit for long-boiled soups.

Note that the soup inside vacuum pots would not be evaporated away. So if you prefer a richer taste of soup, cook the soup over heat for a while right before serving.
