A2: Ginger Ale
Writing in The New York Times, Micheline Maynard describes the ginger ale at Ann Arbor’s Sweetwaters “The Fizz is the latest variation on the ginger-lemon tea, available hot or cold, that Sweetwaters has sold since its original branch in downtown Ann Arbor opened 15 years ago, said Lisa Bee, a co-owner. Both the tea and the ale start with a base of ginger, honey, lemon, water and an ingredient that Ms. Bee declined to identify.” Otherwise put: a secret ingredient. The word “secret” makes it taste that much better. [Source]
