Ramboozle

Ramboozle is a popular British mid-seventeenth century alcoholic beverage, similar to rum. The drink, and its variation, rumfustian, were made by mixing eggs, ale, wine, sugar, and various spices, and then distilling. The names, both British slang, have been linked with the gypsy word rum, meaning "strong" or "potent" (as the drink had a high alcohol content).^[1]
