Chocolate Egg Cream

A new jersey favorite of mine growing up was the chocolate egg cream. There are variations on this but I like this recipe:

1/4 cup cream or half & half (I prefer cream)
1/4 cup Hershey's Chocolate Syrup
Chilled Seltzer

Pour cream or half & half into a tall glass. Pour chocolate sauce in slowly so that it forms a second layer. Slowly add seltzer (until filled) to side of the glass so that the layers remain in tact. Admire, stir, enjoy!
