Use a 10-12 ounce soda fountain glass, filled in the following proportions:

Fill 1/4 of the glass with cold milk. Add vanilla and simple syrup. Then pour seltzer or club soda to the brim of the glass.

A luscious cream colored head will form–drink up!

*If a stronger vanilla flavor is desired, add more, a drop or two at a time, and stir gently.
