Dry shake, shake hard with ice, fine strain into iced 2x rocks glass. Thyme sprig for garnish.
I used a high-quality French clementine purée. To make your own, zest 5 clementines, peel them and add their fruit to a blender. Pour in sugar to taste and a little water and blend briefly to achieve a thick puree. Refrigerate for up to 1 week.
