bain-marie: [19] In its origins, the bain-marie was far from today’s innocuous domestic utensil for heating food over boiling water. It takes its name from Mary, or Miriam, the sister of Moses, who according to medieval legend was an adept alchemist – so much so that she had a piece of alchemical equipment named after her, ‘Mary’s furnace’ (medieval Greek kaminos Marias). This was mistranslated into medieval Latin as balneum Mariae ‘Mary’s bath’, from which it passed into French as bain-marie.

English originally borrowed the word in the 15th century, in semi-anglicized form, as balneo of Mary. At this time it still retained its original alchemical meaning, but by the early 19th century, when English adopted the French term, it had developed its present-day use.

The word comes from Italian caffè espresso, literally ‘pressed-out coffee’, which refers to the way in which the coffee is made by forcing pressurized steam or boiling water through the finely ground beans. Espresso is the past participle of esprimere ‘press out’, from Latin exprimere – which is also the source of English express.
