In a large saucepan combine all of the ingredients and stir while bringing to the boil. Reduce the heat and simmer gently for 1 1/2 hours, stirring occasionally, until thick and well cooked together.
While hot, spoon the chutney into sterilised jars. Seal and leave undisturbed overnight in a cool, dark place until ready to use.
Tip
Use slightly unripe bananas for this recipe for a chunkier texture.
