Bugger, I typed all this once and accidentally deleted it :
2 and a 1/2 lbs. onions
3 tbsns. salt
2lbs. sugar
17 fl. oz. vinegar
1 and a 1/2 tsns. cloves tied in muslin
2 tspns. carraway seeds
Slice onions into thin rings, sprinkle with salt, mix well and leave for an hour. Rinse well and dry.
Put sugar, vinegar and clves into preserving pan. Bring to boil then simmer for 5 mins. Add onions and carraway seeds and bring back to the boil. Turn heat don to minimum and cook for a good 2 hours or until syrup is thick and onions a golden brown.
Take pan off heat and leave for a few minutes for onions to settle then put into hot, sterilised jars and seal.
Improves with keeping a few weeks and will keep for a good two years.
