Chalta acharElephant apple pickle
Chalta, the elephant apple, is a big green fruit of tightly wrapped, fleshy petals, and in Bengal it arrives in the markets in autumn, around Durga Puja, staying through early winter. Raw it is so sour and fibrous that it is almost impossible to eat, but cooked with jaggery and mustard it becomes one of the best-loved sweet-sour pickles of the region. The petals soften into chewy, slightly crunchy pieces in a thick, amber syrup, sour and sweet with a sharp kick of ground mustard and chilli. Serve it with dal and rice at the end of a meal, or with khichuri on a rainy day. The common mistake is skipping the pounding: after boiling, the pieces need a few firm knocks with a pestle to break the fibres, or they stay tough and never absorb the syrup. It is ready when the syrup coats a spoon and the chalta pieces look glossy and translucent. Keep it in a clean jar in the fridge for up to a month. Outside India, frozen chalta is sold in Bangladeshi grocers; hard, sour cooking apples with a squeeze of lime are a passable stand-in. Chef's tip: a pinch of ground mustard added at the very end gives the classic nose-tingling bite.
