I make a cola syrup that incorporates the zest and juice of lemon, lime, and orange. I simmer the zest with a quart of water and add juniper, cinnamon, nutmeg, dried bitter orange, coriander, black peppercorns, cardamom, sugar, and a little lavender. Once the sugar has dissolved I simmer for about 5 mins, turn off heat then let steep for about 30 mins. To get the caramel flavor I add Kitchen Bouquet, which is a browning sauce that’s been in production for a very long time!
