Use granulated sugar and water in proportions of 1 pound of white sugar to 1 pint of water. Stir while bringing water and sugar to a boil until all sugar crystals are dissolved, then permit to cool.
The candying or crystallization of syrup, unless it is over-saturated with sugar, may be prevented by the addition of a little citric acid, 2 or 3 drams (1-1/2 or 2-1/4 teaspoons) per gallon of simple syrup.
Some confectioners add a very little cream of tartar to the sugar to prevent granulation.
Another method for making simple syrup is to use 2 parts granulated sugar to 1 part water.
Bring water to a boil, add sugar and stir so that the sugar is completely dissolved with no sugar crystals visible, then remove from heat and let cool.
Some old time pharmacists recommended adding 1 to 2 teaspoons of corn syrup to help keep the consistency of the simple syrup smooth for storage.
