This New York Cream Rrecipe was shared with me by Bonni Lee Brown, who lives in Bradenton, Florida. Bonni writes, "My Dad made egg creams all the time at his old-fashioned drug store and luncheonette, called Joe Fordham Pharmacy, that was at Kings Highway and East 5th Street in Brooklyn. Egg creams were traditionally made in a small Coca-Coca glass. Two cents plain was both the cost and the name of a plain glass of seltzer. When Dad heard that my mother had given birth to me, around 11:00 a.m., he proudly offered free egg creams to everyone to celebrate!" - Bonni Lee Brown (2008).
Pour 1/2 inch of cold milk into a tall soda glass.
Add seltzer or club soda to within 1 inch of the top of the glass; stir vigorously with a long spoon (this will cause it to become white and bubbly with a good head of foam).
Very gently pour 2 tablespoons of chocolate syrup slowly down the inside of the glass; briskly stir with a long spoon only at the bottom of the glass where the chocolate sits. The resulting drink should have a dark brown bottom and a 1-inch high pure white foam top (if you mix it too much, the foam disappears).
NOTE: Drink Immediately! Do not let the prepared Egg Cream sit for a long period of time (5 minutes or more) as it will go flat.
* Skim or 1% milk will not foam as well.
