Baltimore's signature snowball flavor is 'egg custard,' a pale yellow syrup that tastes nothing like egg and everything like vanilla marshmallow, and is essentially unknown outside the city.
Finely shaved ice is packed into a cup and doused with sweet syrup, often finished with a spoonful of marshmallow topping pressed into the center. Corner snowball stands pop up on Baltimore sidewalks every summer.
