Karonde ka achar
When the thorny karonda bushes along Punjab and Rajasthan field edges fruit in July and August, the small green berries with rosy cheeks end up in jars of karonde ka achar. The fruit is very sour and slightly bitter-milky when raw, so it suits a bold mustard-oil pickle: halved berries and slit green chillies are salted, dried for a day, then tossed with crushed fennel, nigella, fenugreek and mustard. After a week the berries turn soft and sour-tangy, the chillies mellow, and the oil smells of saunf. Eat it with paratha, moong dal khichdi or a plain bowl of curd rice. Karonda is hard to find abroad; firm fresh cranberries are the closest substitute in sourness and size. Common mistake: skipping the drying day; wet fruit thins the oil and invites mould. It is ready when the berries yield to the teeth and the spice coat has darkened. Because it holds fresh green chillies under oil, keep this jar in the fridge for up to 2 months, berries always under oil, dry spoon every time; discard if you see mould, fizzing or an off smell. Chef's tip: wear gloves when halving karonda, the white latex is sticky and stains fingers.
