How to check if haldi is pure (and why it matters)

Turmeric powder is sometimes mixed with rice flour, chalk or bright artificial colours.

1. 1Water test: stir a pinch into a glass of water. Pure haldi settles slowly and leaves the water lightly yellow; dyed haldi turns it bright yellow straight away.
2. 2Palm test: rub a pinch on your palm. Pure haldi leaves a yellow stain that fades; chalky powder feels gritty.

Ground from whole dried roots, with no colour or fillers added.
