You can catch most adulterated ghee at home in a few minutes. Real ghee melts clean on your palm, turns golden-brown (not white) when heated, and dissolves evenly in warm water. None of these need equipment.
Adulteration is the top worry Indian ghee buyers have, and fairly so. Here are six kitchen tests, and one honest note on their limits.
1. The palm test
Put a little ghee on your palm. Pure ghee melts from body heat and smells nutty. If it sits solid or smells oily, be suspicious.
2. The heat and colour test
Heat a spoon of ghee. Pure cow ghee melts fast and turns golden-brown. Adulterated ghee stays pale or whitish, a sign of vanaspati.
3. The melt and set test
Melt it fully, then let it set. Pure ghee sets evenly and slightly grainy. Separation into layers means mixed fats.
4. The refrigerator test
Melt, pour into a clear jar, and refrigerate. Pure ghee solidifies uniformly. Distinct layers point to blended oils.
5. The starch (iodine) test
Add two drops of tincture of iodine to melted ghee. Blue or blue-black means added starch. Pure ghee does not change colour.
6. The water test
Drop a spoon of ghee into a glass of water. Pure ghee tends to stay together and float. Use it alongside the others, not on its own.
The honest limit of home tests
These catch obvious frauds but cannot confirm cow breed, whether A1 milk was blended in, or whether it was truly bilona-made. Only a lab test verifies that, which is why we lab-test every batch of our A2 cow ghee.
Frequently asked questions
What is the easiest way to check ghee purity at home?
The palm test and the heat-colour test: pure ghee melts on the palm with a nutty smell and turns golden-brown when heated.
How do you test ghee for starch?
Add two drops of tincture of iodine to melted ghee. Blue-black means starch. Pure ghee stays unchanged.
