NEW YORK'S CLASSIC EGG CREAM

Steps:

• 1. Squeeze or pour about 2 inches worth of chocolate syrup into a tall 20-ounce glass (such as a Pilsener glass).
• 2. Pour in the milk; DO NOT STIR.
• 3. Hold an inverted soup spoon over the glass. Slowly pour seltzer onto the back of the spoon, letting it cascade into the glass, until the glass is about 3/4 full. Remove the spoon, then add enough seltzer to fill the glass, creating a foamy layer on top.
• 4. Drizzle a few thin lines of chocolate syrup on top of the foamy layer. Insert a straw; serve immediately.
