Cucumber and courgette relish

Another of the preserves I made yesterday was cucumber and courgette relish. This is a sweet preserve and one of my favourites. Remove the seeds and chop. Add some chopped onions (about one third the weight of the cucumber and courgettes).

The vinegar needs to be made as follows: 600ml white wine vinegar, 200g sugar, 40g mustard seeds, 1 tsp celery seeds, 1 tsp turmeric, half tsp ground mace, 1 tsp ground cloves. Bring the vinegar to the boil and leave on the boil for 2 minutes. Then add the cucumber etc and bring it back to the boil. Leave on a boil for only about 2 minutes then add to hot, sterilised jars.
