Wheat Starch Milk (Nishasta)

This traditional method extracts pure wheat starch, historically known as 'wheat milk,' from whole grain berries through a multi-day soaking and fermentation process. The resulting pristine white powder is the essential foundation for making authentic, gelatinous Indian sweets like Ice Halwa and Karachi Halwa, offering a texture superior to commercial cornstarch. Once dried in the sun, this homemade starch can be stored for long periods without spoiling, ready to be transformed into delicate desserts.

Ingredients

4.5 pounds Whole wheat berries (white variety) (Originally '1 Paili'. A Paili is a historical volume measure approx 4-5 lbs.)
2 gallons Water (Quantity estimated for soaking and washing process.)

Instructions

1Pick the wheat berries clean and wash them thoroughly. Place them in a tinned vessel (or stainless steel/glass) and pour enough cold water to completely submerge the wheat with water standing above the grain level. Soak for 3 days. During summer, change the water twice a day; in other seasons, change the water once a day.
2After 3 days, remove the wheat from the water. Crush the softened wheat finely in a mortar or grind it on a clean stone slab (or use a food processor in short bursts) to break open the grains.
3Take a large wide vessel (kathrot) filled with about 4 pounds (approx 2 liters) of cold water. Add the crushed wheat and rub it vigorously with your hands to release the starch. Place a colander or sieve with large holes over a large pot. Pour the wheat and water mixture into it, rubbing the wheat against the sieve with your palm to extract the thick white liquid (milk) into the pot below. Collect the husks remaining in the sieve, crush/rub them again with fresh water two more times to extract any remaining starch, then discard the husks.
4Strain the collected thin milk through muslin or fine cheesecloth to remove any small bran particles. Allow the milk to sit undisturbed for a few hours so the starch settles to the bottom. Once settled, carefully pour off the clear water from the top without disturbing the white sediment. Repeat this rinsing process if necessary to ensure purity.
5Pour the thick white starch sediment into a clean, thick white cloth. Tie it into a bundle and hang it for 12 to 15 hours to drain excess moisture. Open the bundle; the milk will have hardened into a solid block. Cut this into pieces. Spread a clean white cloth on a mat in a sunny spot and place the pieces on it. Dry thoroughly in the sun until absolutely no moisture remains. This prevents souring and ensures the starch stays fresh.
