Potato Starch: Can We Make This At Home?

How to make potato starch at home?

• Use organic golden raw potatoes. Peel it, grate and cut it into small cubes. (You can make potato starch with white potatoes as well).
• Wash and rinse them with cold water.
• After the potatoes are washed and cleaned, it's time to separate the starch. Remember that potatoes have more than 80% water content. More than half of the remainder consists of starch.
• Place the potato cubes in a blender and process until you get a smooth paste. 
• Use cheesecloth and squeeze out the processed potatoes.
• You can add water and rinse the remaining paste a second time to make sure it's free of starch.
• Throw the chaff and filter the liquid.  This will allow the starch to settle in the bottom of the container. It can take between 2 and 4 hours.
• After 2 hours, carefully wash out the dark water, leaving only the white potato starch at the bottom of the container. 
• Sometimes a thin layer of brown water remains, so you can gently pour clean cold water and rinse.
• Pour the thick, starchy, flaky starch into a tray and dry in the sun or over low heat in the oven.
• After drying, squeeze the starch through a fine sieve
• Your homemade starch or potato flour is ready.

Potato starch can last for more than 6 months if you keep it in a dry place and store it in an airtight container.
