Crush an ounce of whole ginger, pour over it a quart of boiling water,
cover the vessel, and let the infusion stand until cold. (The Extract of
Ginger may be used in place of this infusion). Strain through flannel;
add a teaspoonful of Nelson's Citric Acid, six drops of Nelson's Lemon
Flavouring, and a quarter of a pound of lump sugar; stir until
dissolved, and the Gingerade will be ready.
