Turmeric

A ginger relative

Turmeric is closely related to ginger — both are rhizomatous plants in the Zingiberaceae family, both grow as underground tubers, both have similar leaf and stem habits. The flavor profiles are also adjacent — turmeric has a peppery-earthy character with floral notes that’s reminiscent of, but distinct from, ginger’s bright pungency.

In some Asian cuisines, fresh turmeric and ginger are used interchangeably for similar purposes, with turmeric adding the additional dimension of intense yellow color.

The defining color of curry

In Indian cuisine, turmeric is responsible for the characteristic yellow-orange color of curry — the spice typically appears in nearly every Indian curry powder blend, in dal, biryani, and most non-tomato-based stews and braises.

Without turmeric, “curry” would lose its iconic color. The compound responsible — curcumin — is so vivid that turmeric is also widely used as a natural yellow food dye in mustard, cheese, butter, and various commercial products that need a yellow color without artificial dyes.

Ayurvedic medicine and global supplements

In Ayurvedic medicine, turmeric has been used for thousands of years for inflammation, wound healing, digestion, and various health complaints. The medicinal use is so embedded that turmeric is sometimes called “the golden spice” in Ayurvedic literature.

In the 2000s and 2010s, curcumin became a major Western supplement — promoted for anti-inflammatory effects, joint health, brain health, and cancer prevention. The supplement industry around turmeric is now multi-billion-dollar, though the scientific evidence is mixed:

• Solid evidence: anti-inflammatory effects, some benefit for arthritis pain
• Promising evidence: some neuroprotective effects, gut health support
• Weak evidence: cancer prevention claims, most general “wellness” claims
• Bioavailability problem: curcumin is poorly absorbed unless paired with black pepper or specific formulations

Golden milk and turmeric latte

The turmeric latte or “golden milk” became a major café trend in the 2010s — warmed milk (or non-dairy milk) blended with turmeric, ginger, black pepper, honey, and sometimes cardamom or cinnamon.

The drink is rooted in traditional Indian haldi doodh — a centuries-old folk remedy for colds, sore throats, and general illness. Western adaptation typically adds more sweetness and milk-based richness, but the core remains the Ayurvedic formula.

A staining issue

Turmeric stains everything — skin, clothing, plastic containers, wooden cutting boards. The yellow pigment is intense and persistent, surviving washing and bleaching. Indian home cooks use stainless steel or glass bowls when working with turmeric and avoid plastic containers that will be permanently yellowed.

Even brief contact with turmeric can dye fingertips yellow for hours or days. Rubber or latex gloves prevent the staining for those handling large quantities.

Fresh vs dried

Both fresh and dried turmeric have culinary roles:

• Fresh turmeric — sometimes available at South Asian groceries; brighter, more floral, slightly less bitter; common in Southeast Asian curry pastes
• Dried turmeric powder — by far the more common form globally; longer shelf life; more concentrated; used in Indian curries and the spice blends sold worldwide

Most Western cooks only encounter dried turmeric, but fresh turmeric (when available) adds a distinctive dimension worth seeking out.
