Dunk (biscuit)


To dunk or to dip a biscuit or some other food means to submerge it into a drink, especially tea, coffee, or milk. Dunking releases more flavour from confections by dissolving the sugars, while also softening their texture. Dunking can be used to melt chocolate on biscuits to create a richer flavour.

Dunking is a popular way of enjoying biscuits in many countries. A popular form of dunking in Australia is the "Tim Tam Slam", also known as 'tea sucking'. 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.

Dunking is first reported with ancient Romans softening their hard unleavened wafers (in Latin "bis coctum": twice baked) in wine. Modern day dunking has its roots in naval history when, in the 16th century, biscuits known as "hard tack" were on board Royal Navy ships, which were so hard that the British sailors would dunk them in beer in order to soften them up. The most popular biscuit to dunk in tea in the United Kingdom is McVitie's chocolate digestive. In the US, Oreos are frequently dunked in milk, while the Dunkin' Donuts franchise is named for the practice of dunking doughnuts into coffee. In South Africa and in India, rusks are a popular food for dunking in both tea and coffee. In the Netherlands, stroopwaffels are commonly dunked in tea or coffee, often after having been set on above the hot drink for a few minutes to melt the caramel inside.

Dunking is also used as a slang term for intinction: the Eucharistic practice of partly dipping the consecrated bread, or host, into the consecrated wine, by the officiant before distributing.
