Lemonade with citric & tartaric acid
4 cups water
5 cups sugar
rind and juice from 4 lemons
5 tsp citric acid
3 tsp tartaric acid
3 tsp Epsom salts
If you have a food processor, peel the yellow skin from the lemons
with a potato peeler and chop them with a cup of the sugar using
the metal chopping blade. Otherwise, grate them. Bring the water,
sugar grated rind to the boil, then remove from the heat and add
the juice and the carefully measured acids and Epsom salts. (Use
level measuring spoons.) Stir until dissolved, then strain into
clean bottles. Store in refrigerator. For long storage, bottle
immediately, cover tightly, then dip tops in wax when cool.
This cordial is good with iced water, soda water, iced tea, gin,
whisky and rum.
If you are making it only for adult use, add an extra teaspoon of
each of the acids.
