Turmeric is an ubiquitous indian spice and a common ingredient of pre-mixed curry or masala powders. Turmeric (haldi, Konkani; haridra, Sanskrit) is also an essential component of fish marinade.
While I take for granted the turmeric used in cooking, I distinctly remember my grandma preparing scalding hot, turmeric milk whenever we had a sore throat or cold. And grandma admonished us to sip it hot, letting it course its way down the back of our throats. Haaiiii! She had alchemized this common root, to a piping hot, golden elixir, which not only got us back to school the next day (unfortunately), but also back on the playground (v good). Something magical about that turmeric milk! If she only knew!
