Cement mixer

A cement mixer is a shot drink. It often consists of:

The drink is traditionally ingested by taking the shot of Bailey's, holding it in the mouth, then sipping the lime juice and swirling the two around the mouth and/or shaking the head. The drink may also be combined as a layered shot, as the lime juice is less dense than most brands of "Irish Cream". The acidic lime juice causes the cream-based Bailey's to curdle. The curdled Bailey's does not taste sour, but it does rapidly gain viscosity and stick to your teeth, reminiscent of cement. For a sweeter taste, two shot glasses, one of lemonade and one of Bailey's, are used. The shot of lemonade is taken and held in the mouth and is followed by the Bailey's shot--the mixture is then mixed by shaking the head and is then swallowed.

In the The Supersizers Eat...The Eighties episode, the presenters (Giles Coren and Sue Perkins) graphically demonstrate the effect of drinking the Cement mixer cocktail.
