Prepare the fruit and vegetables and place in a heavy based saucepan.
Add the vinegar and bring to a boil, simmering until the fruit and vegetables are tender and the sultanas are beginning to plump. This will take about 20 to 30 minutes.
Add the sugar, salt, pepper and mustard and stir well.
Simmer for another 15 to 20 minutes and then bottle, pouring into warmed, sterilised jars that have been heated in a low oven for 10 minutes.
