kun-JEEL/kənˈdʒiːl/

To become or cause to become thick or solid.

The fat on the soup congeals as it cools.

A close paired view of broth before and after cooling: warm broth has scattered liquid golden fat droplets, while cooled broth has a continuous pale, solidified fat layer that a spoon lifts as a firm sheet.
Etymology

The pieces give “freeze together,” an image of material becoming a solid mass. That freezing sense connects directly with the broader meaning of thickening or setting, especially as something cools.
