History
Louis Auster, a Lower East Side candy-shop owner, claimed the egg cream's invention in the 1890s, using his own chocolate syrup at his Stanton Street shop. Brooklyn's Fox's u-bet syrup, manufactured in Brownsville since 1900, became the editorial standard: a thin, dark, glossy chocolate that emulsifies cleanly with cold whole milk. The name's origin is debated (Yiddish 'echt keem,' real cream; phonetic drift from 'egg cream' as a fancy term for soda-fountain richness; or a working-class joke). What is not debated: the cold-pour technique, milk first, then seltzer hard from the siphon, then syrup whisked in last, makes the foamy white head that signals correctness.
