I'd commissioned this one from Mark Buettler after becoming obsessed with Booker T & The MG's sinewy "Booker's Notion" right around the time I became equally fixated on Booker's Bourbon. I turned Mark onto the song and asked him to create something that channeled its "grimy, slightly dirty" (his words) vibe. Flash forward a year plus and that resulting cocktail has made the second round of Gaz Regan's 101 Best New Cocktails for 2012 at Ardent Spirits. In Gaz's words: "My, oh my. What a bold mother of a drink is this baby. God only knows how Mark came up with this formula. And God only knows why it works so well, but it does. Be careful with this baby. Wait 30 minutes before ordering a second one. Trust me."
