Pour the fluid extract of ginger into a bottle, and add the pumice, shake thoroughly, set aside, and repeat the operation in the course of several hours. Add the water, in the proportion of about 2 ounces at a time, agitating vigorously after each addition. When all is added, repeat the agitation occasionally during 24 hours, then filter, returning the first portion of the filtrate until it comes through bright and clear. If necessary, pass water through the filter, enough to make 12 fluidounces of filtrate.
| VI.— | Strongest tincture of ginger | 1 pint |
|---|---|---|
| Fresh slaked lime. | 1 1/2 ounces | |
| Salt of tartar | 1/4 ounce | |
| VII.— | Jamaica ginger, ground | 32 parts |
| Pumice stone, powdered | 32 parts | |
| Lime, slaked | 2 parts | |
| Alcohol, dilute, sufficient to make | 32 parts |
Rub the ginger with the pumice stone and lime, then moisten with alcohol until it is saturated with it. Put in a narrow percolator, using no force in packing. Allow the mass to stand for 24 hours, then let run through. Filter if necessary.
VIII.—The following is insoluble:
| Cochin ginger, cut fine | 1,000 parts |
| Alcohol, 95 per cent | 2,500 parts |
| Water | 1,250 parts |
| Glycerine | 250 parts |
Digest together for 8 days in a very warm, not to say hot, place. Decant, press off the roots, and add to the colature, then filter through paper. This makes a strong, natural tasting essence.
IX.—Green Ginger Extract.—The green ginger root is freed from the epidermis and surface dried by exposure to the air for a few hours. It is then cut into thin slices and macerated for some days with an equal weight of rectified spirit, which when filtered will yield an essence possessing a very fine aroma and forming an almost perfectly clear solution in water. If the ginger is allowed to dry more than the few hours mentioned it will not produce a soluble essence. It is used in some of the imported ginger ales as a flavoring only, and makes a lovely ginger flavor.
