Just blocks from Tower Grove Park in the Shaw neighborhood of St. Louis lives an ice cream parlor that feels a little like a chemistry lab. Meet Ice’s Plain and Fancy. Start with Ice’s homemade liquid mixture in a flavor of your choosing, add nitrogen (-325 F), stir. Throw in a few ohhh’s and ahhhh’s by my children anxiously watching from behind the glass and you’ve got a recipe for success. We ordered peanut butter vanilla, but I think the beauty of this place lies in the ability to personalize your order.  Since every batch is literally made while you watch you can add or subtract whatever you like. We went with friends on a Friday afternoon, so also indulged in the Boozy Ice Cream treats. A Fruit Loops, Rum Chata and vanilla combo was ordered by the over 21 set. Who knew happy hour could taste this good?
