About
Mashed pumpkin is a dense cooked vegetable purée that weighs slightly more than an equal volume of water.
Mashed pumpkin has a density of about 8.8 pounds per gallon (1.05 g/mL), meaning it sinks in water. Because cooking and puréeing removes air pockets, it packs much more mass into the same space than raw cubed pumpkin. A standard quart container holds about 2.2 pounds (1 kg) of the mixture. Its weight and volume closely match other dense vegetable pastes like sweet potato purée and applesauce.
From Wikipedia
Mashed pumpkin is a vegetable dish made by cooking or macerating the skinless flesh (pulp) of pumpkins and then mashing, straining, grinding, or puréeing until the desired consistency is achieved. It is traditionally served as a side dish, although it has many uses in cooking and baking.
