How To Make Turmeric Powder

Making turmeric powder at home is a straightforward process that allows you to ensure its purity and freshness. Here’s a simple step-by-step guide:

Ingredients and Materials:

  • Fresh turmeric rhizomes (you can find them in the produce section of some grocery stores or at a local market)
  • A clean peeler or small knife
  • A cutting board
  • A blender or food processor
  • A fine mesh sieve or strainer
  • A clean, dry glass jar with an airtight lid for storage


  1. Peel the Turmeric:
    • Start by peeling the outer skin of the fresh turmeric rhizomes. You can use a peeler or a small knife to remove the skin. Be cautious, as turmeric can stain surfaces and clothing.
  2. Slice into Thin Pieces:
    • Once peeled, slice the turmeric into thin pieces. This will help with the drying process.
  3. Dehydrate the Turmeric:
    • There are a few methods for dehydrating turmeric:
      • Sun-Drying: Place the sliced turmeric pieces on a clean, dry surface in direct sunlight. Turn the pieces regularly to ensure even drying. This method may take several days.
      • Oven-Drying: Preheat your oven to its lowest setting. Arrange the turmeric slices on a baking sheet and place them in the oven with the door slightly ajar to allow moisture to escape. Check the turmeric regularly until it is thoroughly dried. This may take a few hours.
      • Dehydrator: Follow the manufacturer’s instructions for your dehydrator to dry the turmeric slices. This method is efficient and can take about 6-8 hours.
  4. Grind into Powder:
    • Once the turmeric slices are completely dehydrated and crisp, transfer them to a blender or food processor. Grind the dried turmeric slices into a fine powder. This may take a few minutes, and you might need to stop and scrape down the sides to ensure an even grind.
  5. Sieve or Strain:
    • If you desire a very fine powder, pass the ground turmeric through a fine mesh sieve or strainer to remove any remaining larger particles.
  6. Store in an Airtight Container:
    • Transfer the freshly ground turmeric powder into a clean, dry glass jar with an airtight lid. Store it in a cool, dark place.


  • Wear Gloves: Turmeric can stain your skin, so consider wearing gloves during the peeling and slicing process.
  • Use Fresh Turmeric: For the best flavor and color, use fresh turmeric rhizomes. However, if you can’t find fresh turmeric, you can use dried turmeric rhizomes instead.
  • Experiment with Ratios: Depending on the size of your turmeric rhizomes and the drying method, you may need to experiment with quantities to get the desired amount of powder.

By making your own turmeric powder at home, you can enjoy the benefits of fresh and unadulterated turmeric in your culinary creations.
