So you know how New Yorkers are all like, try our egg creams! They don’t have egg or cream in them! So crazy! Perhaps even crazier, here’s a recipe (again from The Standard Formulary) for an egg cream with egg AND cream:

Syrup, Egg Cream.
Cream fl. oz. 16
Syrup fl. oz. 48
Extract of vanilla fl. dr. 4
Yolks of 16 eggs.

Rub cream with egg-yolk until perfectly smooth, then add the syrup and flavoring. This is to be served like any other soda syrup, but before handing over, sprinkle a little mixed spice on the foam.

So who wants to blow through a whole bunch of eggs with me?
