Step 1

Combine pear juice, lemon juice, honey, sugar, rosemary, ginger, and nutmeg in a saucepan over medium heat. Bring to a boil, then simmer on low heat for 5 minutes, stirring to dissolve the sugars.

Step 2

Remove from heat and let stand 30 minutes. Strain the syrup through a fine-mesh strainer and discard the solids. Let syrup cool completely.

Step 3

To serve, fill an 8-ounce glass halfway with ice cubes, add 3 tablespoons of syrup, fill with soda water, and stir. Add more syrup for a sweeter or stronger flavor.
