As I mentioned in my previous post, here is a method of making your turmeric powder at home. But let me warn you turmeric is used as textile dye so prepare for stains on your utensils your hands, fingers, nails, as well as your apron, hand towels and anything that you will use
Wash turmeric well and peel lightly.
The result of two days drying under the sun
Use a blender which can grind dry items, or food processor or if you have it, a hammer mill.
Transfer in a container with tight seal/cover. Best to place in the freezer to avoid molds/fungus to develop especially if you are not so sure that your turmeric powder was dried to perfection. Transfer a little amount into a smaller container and place in the lower part of the refrigerator. Refill when used up but keep the main container inside the freezer. Good Luck
