The mysterious Egg Cream, which some say originated on the Lower East Side among Eastern European Jewish immigrants, somehow contains neither eggs nor cream. So, where did that name come from? Some believe “Egg Cream” is an Americanization of “echt keem” — Yiddish for “pure sweetness.” This delightful refreshment is actually made up of only three ingredients: whole milk, soda water, and Fox’s U-bet syrup. The most popular Egg Cream origin story is that it was invented in Brooklyn by candy shop owner Louis Auster during the 1880s. You can still find several places that serve this tasty treat today.
