The Imperial Royale arose in Boston, as a reaction against the seriousness (some might say "pretension") of the modern mixology movement. At its heart, the drink is an elderflower shandy, made of Bud Light Lime and St. Germain elderflower liqueur. Normally a shandy is beer mixed with citrus, lemonade, ginger beer, or cider. The Imperial Royal, pairing a lime-flavored beer and an elderflower liqueur, is simply a variation on that theme.
- 1 (12 ounce) can or bottle Bud Light Lime, chilled
- 2 ounces St. Germain elderflower liqueur
Pour beer into pint glass. Top with St. Germain. Stir gently and serve.
