(n.) A bartending tool used to muddle cocktail ingredients. A long-handled rod with a blunt end, usually made from wood, fancier versions have indentations on the blunt head to better puncture ingredients, but any long instrument with a flat edge, such as a wooden spoon, may be used. It should be long enough that you can keep a good grip on it while performing the muddling action, and it shouldn’t have any varnish or reactive material that could fall into the cocktail.
