Turmeric

Where it comes from

Turmeric is the rhizome of Curcuma longa, a tropical relative of ginger. India produces and consumes roughly 80% of the global crop; Indonesia, Bangladesh, and Sri Lanka grow smaller volumes. The fresh rhizome is harvested in winter, then boiled, dried, and polished into its bright yellow powder form.

Flavor & pairing

Curcumin gives turmeric its punchy yellow-orange color but very little flavor on its own. The taste comes from a suite of essential oils — earthy, mildly bitter, with a peppery sharpness. Turmeric pairs with mustard, ginger, chili, coconut milk, lentils, and yogurt.

How it’s used

Indian curry powders and most South Asian dals begin with a pinch of turmeric in the tadka. Indonesian nasi kuning and Thai yellow curry use it heavily. Middle Eastern pickles and rice dishes color from it. American mustards and pickled relishes get their yellow from turmeric, not mustard seed alone. The recent “golden milk” trend stirs it into warm milk with honey and black pepper.

Trade history

Hindu wedding rituals use haldi turmeric paste on the bride and groom for purification, a tradition at least two thousand years old.
