Eringoes are the sugared roots of the plant Eryngium maritimum, more commonly called 'sea holly'. In Elizabethan times in England, these were believed to a strong aphrodisiac. They are named in a speech by Falstaff: "Let the sky rain potatoes; let it thunder to the tune of Green-sleeves, hail kissing-comfits and snow eringoes, let there come a tempest of provocation..." (source: The Merry Wives of Windsor; Act 5, Scene 5 by William Shakespeare).
