Put the ingredients into a cool oven and let them remain there all night. Next day pound them thoroughly in a marble mortar, and rub through a sieve. Put the powder into a well-corked bottle.
A spice machine may be used instead of the mortar, but in that case the tumeric should be obtained ready powdered, as it is so hard that it is apt to break the machine. The various ingredients are generally only to be obtained from a large wholesale druggist.
