Arrow root mucilage is made by rubbing arrow root powder with a little cold water, in a basin, by means of the back of a spoon, until it is completely mixed with the water; then pouring boiling water over it, stirring assiduously until a soft, gelatinous, tenacious mucilage is formed; and, lastly, boiling for five minutes. A tablespoonful of arrow root powder is sufficient to make a pint of mucilage. It may be moderately sweetened; and wine or lemon juice may be added.
