Candied Orange Peel.
Soak Seville orange-peel in several waters, till it loses its bitterness; then boil it in a solution of double refined sugar in water, till it becomes tender and transparent.
Candied lemon-peel is prepared in the same manner.
It is needless to add more of these preparations, as they belong rather to the art of the confectioner than that of the apothecary.
