Lemon Cordial

This recipe was shown to me by Deirdre Baum from Victoria, Australia.  I spent three weeks woofing on their farm and learned quite a lot of nice recipes.  Cordial is a type of concentrated juice that you mix with water to make refreshing drinks.  Since I got the recipe in Australia the measurements are in metric.

2 kg --- Castor sugar   (Very fine sugar.  You can use household sugar as well)
1 liter --- Water
2 tablespoons --- Citric acid   (Can be picked up at grocery store in baking section)
2 tablespoons --- Tartaric acid  (Can be picked up at grocery store in baking section)
Juice of 6 lemons, strained   (Remove seeds.  A little pulp is ok)
Finely grated zest of 2 lemons

Dissolve sugar in water over heat in a non-reactive stockpot (not a metal pot since the acids will erode the metal.  we used a porcelain cast iron pot).  When the sugar is fully dissolved in the water add the tartaric and citric acid and remove from heat.  Let cool and than add juice and zest.  You can now bottle the cordial for later use.

You can make the cordial even better by mixing it with mint leaves and soda water to get that little sparkle.
