GundrukFermented leafy greens
After the rice harvest in October and November, hill families from Ilam to Gorkha cut the leaves of mustard greens, radish and cauliflower, leave them to wilt in the yard, then pound them into clay pots or pits to ferment. A week later the greens come out olive-brown and sour, and they are dried on bamboo mats in the bright Dashain-Tihar sun. That dried gundruk carries families through the lean winter: soaked and simmered into gundruk ko jhol with tomato and soybeans beside dal-bhat, or tossed into gundruk sadeko with onion, chilli and mustard oil to eat with chiura. The flavour is deeply sour, earthy and a little smoky, the dried leaves chewy-crisp, softening when cooked. Common mistake: packing the leaves loosely; air left in the jar lets mould grow instead of the sour lactic ferment, so press until juice rises over the greens. It is ready to dry when it smells sharply sour like good sauerkraut and the leaves have lost all their green. Chef's tip: if your greens are from a supermarket, mix mustard greens with radish tops or kale for the closest flavour, and ferment in a big jar with a weight.
