Step 1

Put the onions in a large pan with the ginger and vinegar. Bring to the boil, then simmer for 10 mins. Add the rest of the ingredients, except the rhubarb, plus 2 tsp salt to the pan and bring to the boil, stirring. Simmer, uncovered, for about 10 mins until the apples are tender.

Step 2

Stir in the rhubarb and cook, uncovered, until the chutney is thick and jammy, about 15-20 mins. Leave the chutney to sit for about 10-15 mins, then spoon into warm, clean jars, and seal. Label the jars when cool. Keep for at least a month before eating.
