I created this recipe one Christmas, when I noticed a large jar of pickled onions which had been sitting in the fridge for a long time. This is especially good served with daal.
Place a wok on a medium heat, then add the following ingredients in this order: 100ml (3½fl oz/scant ½ cup) hot kettle water, groundnut oil, fenugreek seeds, brown mustard seeds, cumin seeds, nigella seeds, fennel seeds, pickled onions and the vinegar from the jar, jaggery, chilli powder, turmeric, garlic paste, tomato paste and salt t
