Dunk (biscuit)

To dunk is to dip biscuit, bread, cake, or doughnut into a beverage, usually hot, especially tea or coffee, but the popular American snack "milk and cookies" features cookies dunked into cold milk. Dunking a biscuit is said to release flavour, but is usually done to alter the texture of harder confections.

The physics of dunking is driven by the porosity of the biscuit and the surface tension of the beverage. A biscuit is porous and when dunked, capillary action draws the liquid into the interstices between the crumbs.
