2 compounds carry this recipe. Here is what each one does and, where we have it, what it actually looks like.
Tamarind's dominant acid, tartaric acid supplies the deep, mouth-puckering sourness that defines the drink. It is the backbone against which the sugar and salt are balanced.
A secondary acid that lifts the tamarind's heavier sourness with a cleaner, more cooling tartness. It sharpens the overall brightness and makes the cooler read as refreshing rather than merely sour.
This recipe is part of a set: follow the thread through the blends it uses and what it's served with.
Botany files every fruit on earth by its construction: eight Latin words in 1751, a French brawl in 1813, ninety-five types today. Half of them are hiding in your spice drawer.
Every sour thing in the kitchen leads with one particular acid, and the fruit it is named after is usually not where it comes from any more. A look at citric, tartaric, malic and acetic, what each does to flavour, and why vinegar has no legal definition at all.
Arabic traders called it tamr hindi, the date of India. Linnaeus wrote that down as Tamarindus indica in 1753 and the label has held ever since, for a tree that no botanical authority today places in India at all. The name is a receipt from a spice market, and it outlived every fact it got wrong.
