Tonic Water Syrup 4 cups water 4 cups sugar 1/4 cup cinchona bark (try Tenzing Momo) 1/4 cup citric acid Zest and juice of 1 lime Zest and juice of 1 lemon Zest and juice of 1 orange 1 teaspoon coriander seeds (brings out citrus notes) 1 teaspoon dried bitter orange peel (I use Brewers Garden) 10 dashes bitters 1 hand crushed juniper berry Combine all except sugar into a large pot and bring to a boil, turn heat to low and simmer for twenty minutes. Remove from heat and let cool then strain. The cinchona bark is very fine and needs to be fine strained through a french press coffee strainer. Do this in batches and pour all back into a cleaned out large pot. Now you have a strained, brownish tonic base you need to add the sugar to. Bring liquid back to a simmer and add sugar, stir until all the sugar is dissolved. Pour into a food safe container and refrigerate. I have frozen batches when I make a lot and it keeps great. Gin and House Tonic 11/2 oz Gin 3/4 oz Tonic Syrup 2 oz Soda Water Keep in mind that this is a brownish gin and tonic. I have never had a customer who returned one and most people are very open minded to it, especially after they taste it. Homemade tonic is a great conversation starter and don.t be scared to add fruit or whatever to this recipe. Gin and Mango Tonic Water anyone?
