Chocolate egg cream
The egg cream contains neither egg nor cream: it is the old soda-fountain drink of Brooklyn and the Lower East Side, made of cold milk, chocolate syrup and a hard jet of seltzer that whips up a tall white foam. It was sold for pennies at candy stores and corner luncheonettes, and New Yorkers still argue about the right order to pour. Chef's tip: everything, glass included, must be ice-cold, or the foam collapses.
