Sally's Vanilla Egg Creams

I was an extremely rude American yesterday. It was 105º and I practically ordered my neighbor Sally to make one of her famous vanilla egg creams.

Vanilla Egg Creams

cold seltzer
cold milk
vanilla syrup (like the kind at cafés they use to put flavor shots in your coffee) *

Put seltzer in the bottom, then syrup, then milk, then top with seltzer. Serve immediately.

*Torani's "Sugar Free French Vanilla" flavored syrup is not gluten-free, but DaVinci and Monin brands are.
