Beyond the spirit and the juniper berries, you can feel free to experiment with whatever botanicals you like. Some of the most commonly used gin botanicals (after juniper) are coriander seed, angelica root, citrus peel and cassia bark or cinnamon – but feel free to raid the spice cabinet and herb garden. You could try bay leaves, rosemary, liquorice powder, lavender, cardamom, cumin, fennel seeds, lemongrass…pretty much anything you fancy!
