Drinking The World

This is the simplest recipe, and without the extra spice it is very similar to commercial tonic, but with more oomph and unique flavor. I like this one best when you want the character of the gin to shine through.

32 oz H2O
8 whole, crushed, Key Limes weighing 145 grams, 5 oz (You can use the juice and zest of of two regular limes, but don't include the whole lime like you would with the Key Limes.)
1/4 cup / 50 grams Citric Acid (sometimes called Sour salt)
1/2 tsp / 4 grams kosher Salt
1/4 cup / 22 grams chopped Cinchona Bark (Quinine bark)

2 cups cane sugar

I put all the ingredients except the sugar in a sauce pan and brought it to boil, then simmered 40 minutes. I filtered the liquid hot through double coffee filters. This made apx 16 oz liquid. I then added cane sugar to the hot liquid in jar, which topped off to just under 32 oz. I shook it to melt the sugar.

Use at the same strength as the previous recipes, or to taste.
