Add the water to the saucepan over high heat. Stir in the salt, sugar, peppercorns, coriander seeds, garlic, shallot, juniper berries, bay leaf, and rosemary. While the mixture comes to a boil, add the ice to a large bowl. Once the mixture comes to a boil, add it to the ice and stir. The mixture will cool down quickly.
