Punjabi orange pickle

Method

1. Cut a slice of peel off the top and bottom of each orange and discard. Working from top to bottom, slice away the skin of each orange in strips, making sure to remove all the white pith. Working over a bowl to catch the juice, remove the orange segments by slicing as close to the membrane of each one as you can, then sliding them out onto a board. Squeeze out as much juice as you can from the pulp and discard any pips.
2. Cut the strips of orange peel into chunky slices as you would for marmalade. Put the peel into a large, deep pan with the onions and vinegar and strain over the juice from the oranges. Bring to a simmer, cover, then continue simmering for 30 minutes until the peel is soft.
3. Cut the orange segments into chunks, then stir into the mixture with the rest of the ingredients (see Know-how, left). Bring to the boil, lower the heat and simmer for about 1½ hours, stirring regularly and more frequently as the mixture thickens towards the end of cooking. It should have the consistency of jam (remember that it will thicken a little more as it cools).
4. Spoon the pickle into warm, sterilised jars and cover with waxed discs, then seal with the lids.
